Subject: [PATCH 008/583] V4L/DVB (9361): Dynamic DVB minor allocation

Implement dynamic minor allocation for DVB, to allow more than four
devices of the same type per adapter, based on drivers/usb/core/file.c.

Add a new config option, DVB_DYNAMIC_MINORS, to make use of this
feature, which defaults to no for backwards compatibility.

+	  allocation for any device that uses the DVB major number.
+	  This means that you can have more than 4 of a single type
+	  of device (like demuxes and frontends) per adapter, but udev
+	  will be required to manage the device nodes.

Subject: [PATCH 011/583] V4L/DVB (9364): adding sharp s921 ISDB-T driver

s921_module.c:
    wrapper for the dvb frontend interface
    s921_core.c:
    core s921 1seg ISDB-T driver, everything is set to auto as much as possible
    in order to not require certain parameters which currently cannot be passed
    to the ISDB-T chip.

    ISDB-T support can be tested using dvbscan, dvbstream/snoop and mplayer
    Tested 1seg H264/aac stream with this driver using a custom linux
ISDB-T player

 audio

 	- Most tuner chips do provide mono sound, which may or may not
 	  be useable depending on the board design.  With the Hauppauge
 	  cards it works, so there is mono sound available as fallback.
 	- audio data dma (i.e. recording without loopback cable to the

Subject: [PATCH 022/583] V4L/DVB (9381): On the KNC1 cards the CLOCK is
 clamped to a maximum limit of 90MHz, eventhough

not limited in hardware, this causes instabilities at a higher clock due to
issues such as thermal, also the divider wraps around, which causes the
demodulator core to actually run at a lower frequency. This needs to be
empirically tested whether it affects other cards. If found necessary, this
parameter needs to be moved out to the config struct such that it can be made
hardware dependant.

Reducing the CLOCK from 99MHz to 90MHz improved the acquisition time taken on
the KNC1 cards and hence such a change.

Subject: [PATCH 045/583] V4L/DVB (9405): Practical tests show that the TT S2
 3200 has I/Q inputs inverted, similar to the KNC1.

Don't have this hardware and cannot verify this for myself, but from the reports this
looks to be quite a reasonable and correct hypothesis.

Subject: [PATCH 062/583] V4L/DVB (9423): Though insignificant, removes an
 unnecessary read of the LOCK_LOSS register,

which should have happenend in the DVB-S2 mode only, but reading it as it is
for the other delivery systems causes nothing to say but LOCK_LOST, which
just causes confusion amongst users.

Subject: [PATCH 069/583] V4L/DVB (9430): stb0899: avoid parameter overwriting

BUG! Setting CRL parameter overwrote the CR Algorithm type,
eventually leading to wrong search algorithm to be employed in
the DVB-S carrier loop optimization.

Symptom: Once the CR optimization stage is passed either way, in
a successful or failed manner, the very next carrier search will
fail, due to no Carrier Search Algorithm specified.

Subject: [PATCH 072/583] V4L/DVB (9433): Limit bandwidth with a 3dB response
 fall

In this case, we will be sure that there exists a carrier
and the center frequency would be simply f1 - f2. In such
a circumstance, the TR loop is simplified to doing a simple
check for timing, rather than searching for the same.

Subject: [PATCH 078/583] V4L/DVB (9439): Bug! SFRL nibble got swapped

The Bug was found by Arvo Jarve <arvo@softshark.ee>

It was a wonder how it worked in the case with this bug,
STM verified this that this nibble was in fact insignificant
and can be ignored.

But still we need to fix all inconsistencies.

Subject: [PATCH 081/583] V4L/DVB (9442): Revert back previous change to 90MHz

Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
  incoming symbols and hence might run into problems at the very end of the
  specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
  running at 90MHz, raises lot of issues such as the need to recalculate
  all of them , which is eventually very painful.

Subject: [PATCH 082/583] V4L/DVB (9443): Bug: Bandwidth calculation

Bug #1: The 5 tap equaliser is set to correct simple perturbations
like reflections on the IF cable for DVB-S. In the case of DVB-S2
a more powerful equalizer is used to correct the filter group delay
allowing the bandwidth to be reduced by a factor of 1/3

Bug #2: The ZIF tuner takes badwidth to be set in Hz

Optimizations galore: Blistering barnacles! The KNC1 and friends
like 90 Mhz clock much better rather than running at a higher
throttle, for almost similar hardware. he exact cause unknown,
possibly due to a lower voltage applied for the demod power supply.

Subject: [PATCH 102/583] V4L/DVB (9463): Make delivery system standalone.

Eventhough the delivery system is made standalone, DVBFE_SET_DELSYS
needs to be set as the very first operation, for a multistandard frontend

Splitting delivery system out as a new ioctl, makes things a bit more
easier to understand.

 pci_dma_mapping_error

pci_dma_mapping_error can't be used for pci_alloc_consistent
(pci_dma_mapping_error is for dma_map_single and dma_map_page).
pci_alloc_consistent returns NULL if the allocation fails.

Subject: [PATCH 116/583] V4L/DVB (9490): linux-next: v4l-dvb tree build
 failure

Today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/media/dvb/dvb-core/dvbdev.c: In function 'dvb_register_device':
drivers/media/dvb/dvb-core/dvbdev.c:254: error: implicit declaration of function 'nums2minor'

Caused by commit f3d9182030d9655d9ffff33dfceb45b4a127b6ec ("V4L/DVB
(9361): Dynamic DVB minor allocation") which clearly has not even been
built with CONFIG_DVB_DYNAMIC_MINORS=y.

Subject: [PATCH 122/583] V4L/DVB (9503): v4l: remove inode argument from
 video_usercopy

The inode argument was never used. Removing it from video_usercopy
brings the function pointer type of video_usercopy in line with similar
v4l2 functions, thus simplifying several drivers.

Subject: [PATCH 126/583] V4L/DVB (9512): cx18: Fix write retries for registers
 that always change - part 3.

cx18: Fix write retries for registers that always change - part 3.
Fix the io for the rest of the registers that will often not read back the
value just written.  Modified register readback checks to make sure the
intended effect was achieved without constantly rewriting the registers.
The one outstanding register remaining is 0xc72014 CX18_AUDIO_ENABLE, whose
behavior on writes I have yet to determine.

Subject: [PATCH 129/583] V4L/DVB (9521): V4L: struct device - replace bus_id
 with dev_name(), dev_set_name()

This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

Thanks,
Kay

Subject: [PATCH 130/583] V4L/DVB (9522): Increase number of SAA7134 devices
 supported in a system

The SAA7134 device driver currently only supports 8 such devices in a
system. This is too small for many surveillance applications. This
patch increases the number to 32.

Subject: [PATCH 158/583] V4L/DVB (9569): uvcvideo: Sort the frame descriptors
 during parsing

The UVC specification does not require frame descriptors to be sorted by
bFrameIndex. At least one camera (145f:013e) is known not to sort the
descriptors properly, so they need to be sorted during parsing as the driver
then accesses them by index.

Subject: [PATCH 160/583] V4L/DVB (9539): dsbr100: add suspend and resume

This patch adds support for suspend and resume methods in driver.
Without this kradio and gnomeradio crashes during resume.
Also .supports_autosuspend in usb_driver struct set equal to 0 to avoid
suspending of module if usb_autosuspend enabled.

Subject: [PATCH 164/583] V4L/DVB (9563): gspca: Let gspca handle the webcam
 0471:0328 instead of sn9c102.

According to http://bugzilla.kernel.org/show_bug.cgi?id=11997,
the driver sn9c102 does not work for this webcam.

Subject: [PATCH 165/583] V4L/DVB (9570): uvcvideo: Handle failed video
 GET_{MIN|MAX|DEF} requests more gracefully

Failed requests will now generate a one-time warning message instead of the
usual "Failed to query..." error, which should be more user-friendly. The
driver will also recover automatically from failed GET_MIN/GET_MAX requests
when the device is half-broken without requiring the MINMAX quirk (fully
broken devices still need the quirk).

Subject: [PATCH 176/583] V4L/DVB (9585): Skip reading eeprom in newer Empia
 devices

Empia switched to a 16-bit addressable eeprom in newer devices.  While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms).  So just be safe and bail out of the function.

Thanks for Ray Lu from Empia for providing the em2874 datasheet.

Subject: [PATCH 183/583] V4L/DVB (9607): em28xx: Properly implement poll
 support for IR's

The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.

This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.

This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.

Subject: [PATCH 186/583] V4L/DVB (9628): em28xx: refactor IR support

Refactor the em28xx IR support based on the em2860/em2880 and em2874
datasheets.

Tested on the HVR-950 (em2883), Pinnacle 800e (em2883), Pinnacle 80e (em2874)
using the remote controls that came with those products.

 end of attach() call

Place the s5h1411 into low power mode until first use (to handle the case where
the user plugs in the device and then doesn't use it for a while).  On the
Pinnacle 801e, this brings the power usage from 126ma down to 82ma.

Subject: [PATCH 192/583] V4L/DVB (9638): drivers/media: use ARRAY_SIZE

ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>

Subject: [PATCH 200/583] V4L/DVB (9651): em28xx: Improve audio handling

This patch properly implements audio handling on em28xx. Before this
patch, it was assumed that every device has an Empia 202 audio chip.
However, this is not true.

After this patch, specific AC97 chipset setup and configurations can be
done.

Subject: [PATCH 201/583] V4L/DVB (9652): em28xx: merge AC97 vendor id's into a
 single var

This makes easier to identify vendor ID, since AC97 vendors are
generally identified by 3 bytes. The remaining byte is used by the
vendor to identify its devices.

Subject: [PATCH 202/583] V4L/DVB (9653): em28xx: improve AC97 handling

AC97 devices provide several input and outputs. However, before this
patch, em28xx device weren't properly allowing the usage of ac97
possible combinations. Also, several input volumes were left untouched,
instead of making sure that the volumes were set on mute state.

This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.

Yet, some work is still needed to select the AC97 output.

Subject: [PATCH 204/583] V4L/DVB (9657): em28xx: add a functio to write on a
 single register

Introduce a new function that writes to a single register.  This is
useful because the vast majority of register writes are a single
register, and this format permits or'ing register value bits together.

Subject: [PATCH 208/583] V4L/DVB (9661): uvcvideo: Commit streaming parameters
 when enabling the video stream

Sonix-based cameras seem to require the host to commit video streaming
parameters before selecting the alternate endpoint. While most applications
issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required
by the V4L2 specification.

The problem has been noticed on Ubuntu 8.10 with applications using libv4l.
The library blocks VIDIOC_S_FMT calls when the requested format is identical
to the currently selected format. As the driver commits video streaming
parameters when initialising the device, only the first run of a
libv4l-enabled application would succeed.

For the sake of completeness, experiment showed that the camera keeps sending
12 bytes isochronous packets (header only, no data) without toggling the FID
bit if video streaming parameters haven't been committed before selecting the
alternate endpoint.

Subject: [PATCH 209/583] V4L/DVB (9662): uvcvideo: Fix printk badness when
 printing ioctl names

Add a trailing newline character after calling v4l_printk_ioctl() to avoid
messing the kernel log up and merge the uvc_v4l2_ioctl message with the ioctl
name.

Subject: [PATCH 210/583] V4L/DVB (9665): af9015: Add support for the
 Digittrade DVB-T USB Stick remote

Adds support for the Digittrade DVB-T USB Stick remote.
As the Digittrade USB stick identifies itself as a generic Afatech AF9015
device, the remote cannot be autodetected. To enable it, add the following
to /etc/modprobe.d/dvb-usb-af9015 or /etc/modprobe.conf:

options dvb-usb-af9015 remote=4

Subject: [PATCH 213/583] V4L/DVB (9670): em28xx: allow specifying audio output

Some boards use different AC97 setups for output. This patch adds the
capability of specifying the output to be used. Currently, only one
output is selected, but the better is to allow user to select it via a
mixer, on alsa driver.

Subject: [PATCH 224/583] V4L/DVB (9685): gspca: Correct restart of webcams in
 spca501.

Currently the spca501 driver only works the first time used, then the cam needs
to be unplugged or the driver reloaded, this is because currently the data
which should be send each time the stream is started is send only once.
Likewise currently the data to initialize the cam is send from the probe
function, and thus will not get send after a suspend/resume.
This patch fixes this by sending both at the right time.

From fbb4c6d20f29f2b10daad31cc6238d91f93d70d4 Mon Sep 17 00:00:00 2001
From: Antonio Ospite <ospite@studenti.unina.it>
Date: Sat, 22 Nov 2008 05:23:39 -0300
Subject: [PATCH 239/583] V4L/DVB (9712): gspca:Subdriver ov534 added.

The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE,
it is found also in other webcams like Hercules Blog Webcam and
Hercules Dualpix HD.
This driver is the port to gspca of a prototype driver by Mark Ferrell
based on vivi. The original code to initialize the camera and start the
capture is from Jim Paris on ps2dev.org, here integrated with the analysis
of the USB communications taken by the windows driver.

Subject: [PATCH 241/583] V4L/DVB (9717): em28xx: improve message probing logs

On some em28xx devices, there's an unused interface. This is printed on
the logs as an error. We can just ignore that interface.

Subject: [PATCH 251/583] V4L/DVB (9747): em28xx: Properly handles XCLK and I2C
 speed

The previous patches removed XCLK and I2C magic. Now, we finally know
what those registers do. Also, only a very few cards need different
setups for those.

Instead of keeping the setups for those values inside the per-device
hack magic switch, move the uncommon values to the board-specific
struct, and have a common setup for all other boards.

So, almost 100 lines of hacking magic were removed.

A co-lateral effect of this patch is that it also fixes a bug at em28xx-core, where xclk
were set, without taking any care about not overriding a previous xclk setup.

From d4d889e329bd0837598b3ef611806421754e9b83 Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Tue, 25 Nov 2008 09:10:25 -0300
Subject: [PATCH 252/583] V4L/DVB (9751): em28xx: card description cleanups

Remove unused em28xx_board.vchannels and em28xx.video_channels.
Also, .is_em2800 = 0 is not needed, as all data is zeroed by kernel loader.

The table also included a notice that svideo weren't test on Hauppauge
USB2. Remove this notice, since this input also works properly.

Also, it does some whitespace cleanups.

From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Tue, 25 Nov 2008 09:39:50 -0300
Subject: [PATCH 253/583] V4L/DVB (9752): Remove duplicated fields on
 em28xx_board and em28xx structs

Several fields are duplicated on both structs. Let's just copy em28xx_board instead.

A later cleanup could just copy the fields that are changed, in order to keep em28xx_board
const.

From ec5de990d912c0d5cca98e030bf6447c1529f56d Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Tue, 25 Nov 2008 09:43:29 -0300
Subject: [PATCH 254/583] V4L/DVB (9753): em28xx: cleanup: saa7115 module
 auto-detects saa711x type

Since saa7115 has saa711x chip auto-detection, there's no need on differenciating
it at cards table. Just use the generic name for all boards that use a philips
saa711x decoder.

Subject: [PATCH 255/583] V4L/DVB (9754): em28xx: improve debug messages

Now, the first message states board names. Also, removed printing the alternate
settings by default. I2C messages are now clearer.

Subject: [PATCH 257/583] V4L/DVB (9758): em28xx: replace some magic by
 register descriptions where known

Replaces all occurrences of em28xx_write_regs_req() and em28xx_write_reg()
used to setup register names by em28xx_write_reg().

Also, documents the register names that are known.

This patch were generated by this small perl script:

my %reg_map = (
	# Register table - the same as defined on parse_em28xx.pl script
);

while (<>) {
	if (m/(.*)em28xx_write_regs_req\(dev\,\s*0x00\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
		my $reg = $2;
		my $val = $3;
		$val =~ tr/A-f/a-f/;
		$reg = $reg_map{$reg} if defined($reg_map{$reg});
		printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
	} elsif (m/(.*)em28xx_write_regs\(dev\,\s*(.*)\,\s*\"\\x(..)\",\s*1\)\;(.*)/) {
		my $reg = $2;
		my $val = $3;
		$val =~ tr/A-f/a-f/;
		$reg = $reg_map{$reg} if defined($reg_map{$reg});
		printf "$1em28xx_write_reg(dev, %s, 0x%s);$4\n", $reg, $val;
	} else {
		print $_;
	}

Subject: [PATCH 259/583] V4L/DVB (9760): em28xx: move gpio lines into board
 table description

Instead of a large, ugly switch specifying the gpio tables for each
device, let's move it into the boards struct. This also helps to see
what boards have already the gpio's for DVB.

Subject: [PATCH 261/583] V4L/DVB (9762): em28xx: fix tuner absent entries

Before this patch, several devices without tuner were kept the value 0
for tuner_type. However, this means TUNER_TEMIC_PAL. Replace those
entries for the proper TUNER_ABSENT value.

 device when not used

Several chips may be turned off when the device is not used, like audio,
video and dvb demods. This patch adds a gpio callback at the core
structs to allow turning off such devices.

Subject: [PATCH 269/583] V4L/DVB (9442): Revert back previous change to 90MHz

Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
  incoming symbols and hence might run into problems at the very end of the
  specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
  running at 90MHz, raises lot of issues such as the need to recalculate
  all of them , which is eventually very painful.

Subject: [PATCH 270/583] V4L/DVB (9513): cx18: Reduce number of mmio read
 retries

cx18: Reduce number of mmio read retries to improve performance.  Experiments
have shown 2 things: read retries never improve the result of a suspect mmio
read from the CX23418 (the result stays all 0xff's), and that most of the
suspected read failures are actually proper reads of values that should be
all 0xff's.  This change reduces the number of read retries and keeps the
count separate from write retries.

Subject: [PATCH 272/583] V4L/DVB (9592): cx18: Use default kernel work queue;
 fix streaming flag for work handler

cx18: Use default kernel work queue; fix streaming flag for work handler.
Eliminate cx18 specific work queue and use the kernel default work queue.
Fixed the F_STREAMING_FLAG for the TS stream so cx18_dvb_work_handler()
can know when it is not safe to send MDLs to the firmware.

Subject: [PATCH 273/583] V4L/DVB (9593): cx18: Add outgoing mailbox mutexes
 and check for ack via waitq vs poll

Add mutexes to ensure exclusive access for outgoing driver to CX23418 mailboxes.
Also wait on a waitq for mailbox acknowledgement from the CX23418 instead of
polling.

Subject: [PATCH 275/583] V4L/DVB (9595): cx18: Improve handling of outgoing
 mailboxes detected to be busy

cx18: Improve handling of outgoing mailboxes detected to be busy.  When
encountering a busy mailbox, sleep instead of polling, and wait for interrupt or
timeout.  If the mailbox is still busy, force it free.  When sending commands,
make sure we never create a situation where we mark the mailbox busy upon
sending, and ensure we always have a method to cleanly recover from a busy
mailbox.

 mailbox protocol integrity & performnce

All waits for cx18 mailbox API commands are now uninterruptable.  Added
code to collect mailbox ack statistics.  Tweaked timeouts based on collected
stats and video vertical frame and field rates.

Subject: [PATCH 278/583] V4L/DVB (9598): cx18: Prevent CX23418 from clearing
 it's outgoing ack interrupts to driver

When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for.  This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver.  This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.

 problem upon APU firmware file read failure

If APU firmware file read failed, the jump vector to the APU was undefined and
the APU would be started executing garbage.  Fix uninitialized variable to be
an infinite loop for the APU, but also bail out before even starting the APU.

Subject: [PATCH 283/583] V4L/DVB (9720): cx18: Major rewrite of interrupt
 handling for incoming mailbox processing

A major rewrite of interrupt handling for incoming mailbox processing, to split
the timing critical steps from the the deferrable steps as the sending XPU on
the CX23418 will time out and overwrite our incoming mailboxes rather quickly.
Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work.  Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.
Future optimizations will get rid of mmio read retries, mmio stats logging, and
combine smaller functions in the irq path into the larger ones to save ~2 us
each.

From: Andy Walls <awalls@radix.net>
Date: Sun, 16 Nov 2008 17:15:01 -0300
Subject: [PATCH 284/583] V4L/DVB (9721): cx18: Change to singlethreaded global
 work queue thread for deferable work

Change to singlethreaded global work queue thread for deferable work,
instead of the kernel default multithreaded work queue.  This ensures
execution of deferable work is always in the proper order, so caputred buffers
don't get reordered.

Subject: [PATCH 285/583] V4L/DVB (9722): cx18: Convert per stream queue
 spinlocks into mutexes

Convert the per stream queue spinlocks into mutexes.  All queue
manipulation happens via the work queue or system calls into the driver, and
not in an interrupt context.  This reduces the amout of time the cx18 driver
keeps interrupts disabled.

Subject: [PATCH 286/583] V4L/DVB (9723): cx18: Propagate staleness of mailbox
 and mdl ack data to work handler

cx18: Propagate staleness of mailbox and mdl ack data to work handler to let
the work handler know that the data from the encoder may not be coherent.
Allows for smarter handling of buffers in future, to deal with MDLs that fall
out of rotation due to irq handler being late in collecting mailbox and mdl ack
info.

cx18: Streamline cx18-io[ch] wrappers and enforce MMIO retry strategy so that
write retries always occur and read retries never occur (as they never help).
Remove MMIO statistics logging to speed up MMIO accesses.  Deprecate & ignore
retry_mmio and mmio_ndelay module parameters, to essentially force
retry_mmio=1 and mmio_ndelay=0.

Subject: [PATCH 288/583] V4L/DVB (9725): cx18: Remove unnecessary MMIO
 accesses in time critical irq handling path

Remove unnecessary MMIO accesses in time critical irq handling path.  Also
ensured that the mailbox ack field is read in last, so we know for sure if we
have a stale mailbox or not on receipt.

Subject: [PATCH 290/583] V4L/DVB (9727): cx18: Adjust outgoing mailbox
 timeouts and remove statistics logging

cx18: Adjust outgoing mailbox timeouts and remove statistics logging.
This saves some wasted storage in struct cx18 for each card.  Cutting
the outgoing mailbox timeouts in half from the previous value appears to
be safe with MythTV.  Got rid of interrupted case code path after
a wait uninterruptable returns.

 warning that often has benign consequences

Subject: [PATCH 296/583] V4L/DVB (9769): tuner-xc2028: powers device of when
 not used

Since the firmware load is now fast on most boards, better to keep the tuner
off by default. A modprobe parameter were added to keep the old behavior,
to be used by old devices.

Subject: [PATCH 297/583] V4L/DVB (9770): em28xx: turn off tuner when not used

em28xx devices generally get hot when xc3028 tuner is powered on. This
patch solves this by turning power off when the device is not used, at the
expense of having a higher load time, when calling a TV application.

Since firmware load happens on 1 or 2 seconds on most devices, this is not a pain.

Also, it helps to save the planet by saving some power :)

Subject: [PATCH 301/583] V4L/DVB (9774): tda827x: fix returned frequency

Probably due to a removed code, tda827x were doing some wrong calculus at the
returned frequency. I suspect that the original idea were to return the
programmed divisor converted into frequency again.

However, the current code is sometimes multiplying the programmed frequency by
62500, and, on other cases, like radio, it dividing it by 1000.

Instead of doing such math, let's just store the frequency value as requested by
the caller module.

Subject: [PATCH 302/583] V4L/DVB (9775): tda8290: fix FM radio

tda8290 were using some random video standard for FM. This results on random
errors. Instead, program tda8290 in expert mode, using a configuration near the
one specified on NXP datasheet for tda8295 (available on their site).

Also, properly display that the device is on radio mode.

 work queues for deferrable work handling

cx18: Change to per CX23418 device work queues for deferrable work handling.
Needed to support 2.6.22 and earlier kernels that can't selectively cancel
work orders.  Also will provide slightly better performance on SMP systems.

Subject: [PATCH 304/583] V4L/DVB (9778): cx18: cx18_writel_expect() should not
 declare success on a PCI read error

cx18: cx18_writel_expect() should not declare success on a PCI read error.
This removes the potential for cx18_write*_expect() calls to not
accomplish a PCI write successfully as expected.  The CX18-AV core uses the
*expect() calls often and this may be the source of intermittent audio
problems and standands switching problems.

Subject: [PATCH 307/583] V4L/DVB (9785): soc-camera: merge .try_bus_param()
 into .try_fmt_cap()

.try_bus_param() method from struct soc_camera_host_ops is only called at one
location immediately before .try_fmt_cap(), there is no value in keeping these
two methods separate, merge them.

Subject: [PATCH 309/583] V4L/DVB (9787): soc-camera: let camera host drivers
 decide upon pixel format

Pixel format requested by the user is not necessarily the same, as what
a sensor driver provides. There are situations, when a camera host driver
provides the required format, but requires a different format from the
sensor. Further, the list of formats, supported by sensors is pretty static
and can be pretty good described with a constant list of structures. Whereas
decisions, made by camera host drivers to support requested formats can be
quite complex, therefore it is better to let the host driver do the work.

Subject: [PATCH 310/583] V4L/DVB (9788): soc-camera: simplify naming

We anyway don't follow the s_fmt_vid_cap / g_fmt_vid_cap / try_fmt_vid_cap
naming, and soc-camera is so far only about video capture, let's simplify
operation names a bit further. set_fmt_cap / try_fmt_cap wasn't a very good
choice too.

Subject: [PATCH 312/583] V4L/DVB (9790): soc-camera: pixel format negotiation
 - core support

Allocate and fill a list of formats, supported by this specific
camera-host combination. Use it for format enumeration. Take care to stay
backwards-compatible.

Camera hosts rely on sensor formats available, as well as
host specific translations. We add a structure so that hosts
can define a translation table and use it for format check
and setup.

Subject: [PATCH 313/583] V4L/DVB (9791): pxa-camera: pixel format negotiation

Use the new format-negotiation infrastructure, support all four YUV422
packed and the planar formats.

The new translation structure enables to build the format
list with buswidth, depth, host format and camera format
checked, so that it's not done anymore on try_fmt nor
set_fmt.

Subject: [PATCH 316/583] V4L/DVB (9796): drivers/media/video/cx88/cx88-alsa.c:
 Adjust error-handling code

In the function cx88_audio_initdev, the value card has been created using
snd_card_new.  The other error handling code in this function frees the
value using snd_card_free.  I have thus changed the first error case to do
the same.  On the other hand, it may be that card is not sufficiently
initialized at this point to use snd_card_free, in which case something
else should be done to free the memory in the error case.

In the function snd_cx88_create the call kfree(chip) in one error case
looks suspicious, both because it is not done in the other error code, and
because chip points into the middle of the memory allocated by
snd_card_new, ie it is not itself associated with a separate kmalloc.
Therefore I have removed it.

The semantic match that finds the first problem is as follows:

Subject: [PATCH 320/583] V4L/DVB (9800): cx18: Eliminate q_io from stream
 buffer handling

Eliminate q_io from stream buffer handling in anticipation of upcoming
changes in buffer handling.  q_io was a holdover from ivtv and it's function
in cx18 was trivial and not necessary.  We just push things back onto the
front of q_full now, instead of maintaining a 1 buffer q_io queue.

Subject: [PATCH 321/583] V4L/DVB (9801): cx18: Allow more than 63 capture
 buffers in rotation per stream

cx18: Allow more than 63 capture buffers in rotation per stream.  Implement
q_busy to hold buffers the firmware has for use.  q_free holds truly unused
buffers in a pool.  New buffers are given to the firmware as soon as the
firmware returns one, if there are any to give to the firmware.

From 6ecd86dcc838fa446ec86334a9fe0c1e415e3514 Mon Sep 17 00:00:00 2001
From: Andy Walls <awalls@radix.net>
Date: Sun, 7 Dec 2008 23:30:17 -0300
Subject: [PATCH 322/583] V4L/DVB (9802): cx18: Add module parameters for finer
 control over buffer allocations

cx18: Add module parameters for finer control over buffer allocations.
User now has the option of setting smaller buffers to get lower
latency transfers from the encoder.  User can also now set the number
of buffers used for a stream explicitly.

Subject: [PATCH 324/583] V4L/DVB (9804): cx18: Avoid making firmware API calls
 with the queue lock held

cx18: Avoid making firmware API calls with the queue lock held.  The source
of MPEG strem corruption when not holding the queue lock was found to be that
the MPEG buffer could be retrieved by the user app before it was sync'ed for
the host cpu.  Incoming buffers are now sync'ed before being put on q_full and
releasing the queue lock.  We can thus avoid the sometimes lengthy call to
the firmware for CPU_DE_SET_MDL while holding the queue lock, so we can get
better performance.

Subject: [PATCH 325/583] V4L/DVB (9805): cx18: Port fix for raw/sliced VBI
 mixup from ivtv and cx25840

This is a port of the fixes Hans Verkuil made for ivtv/cx25840:
The service_set field was used to determine whether raw or sliced VBI was
desired. This is incorrect since it is perfectly valid to select sliced VBI
with a service_set of 0.

Instead the driver should check on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.

Updated the cx18 driver accordingly, including an additional check in
cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

Subject: [PATCH 326/583] V4L/DVB (9806): cx18: Enable raw VBI capture

A combined authorship patch from Hans Verkuil and Andy Walls.  Raw
VBI can now be captured but requires a video capture to be in progress as well.

Subject: [PATCH 327/583] V4L/DVB (9809): uvcvideo: Add nodrop module parameter
 to turn incomplete frame drop off.

The driver drops incomplete uncompressed video frames to avoid confusing
userspace with corrupt data. Add a nodrop module parameter to turn that
behaviour off and make all frames available to userspace.

+How to set up the Technisat devices
+===================================
+
+1) Find out what device you have
+================================
+
+First start your linux box with a shipped kernel:
+lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
+02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
+
+dmesg | grep frontend may show you for example:
+DVB: registering frontend 0 (Conexant CX24123/CX24109)...
+
+2) Kernel compilation:
+======================
+
+If the Technisat is the only TV device in your box get rid of unnecessary modules and check this one:
+"Multimedia devices" => "Customise analog and hybrid tuner modules to build"
+In this directory uncheck every driver which is activated there.
+
+Then please activate:
+2a) Main module part:
+
+a.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters"
+b.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters" => "Technisat/B2C2 Air/Sky/Cable2PC PCI" in case of a PCI card OR
+c.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters" => "Technisat/B2C2 Air/Sky/Cable2PC USB" in case of an USB 1.1 adapter
+d.)"Multimedia devices" => "DVB/ATSC adapters" => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters" => "Enable debug for the B2C2 FlexCop drivers"
+Notice: d.) is helpful for troubleshooting
+
+2b) Frontend module part:
+
+1.) Revision 2.3:
+a.)"Multimedia devices" => "Customise DVB frontends" => "Customise the frontend modules to build"
+b.)"Multimedia devices" => "Customise DVB frontends" => "Zarlink VP310/MT312/ZL10313 based"
+
+2.) Revision 2.6:
+a.)"Multimedia devices" => "Customise DVB frontends" => "Customise the frontend modules to build"
+b.)"Multimedia devices" => "Customise DVB frontends" => "ST STV0299 based"
+
+3.) Revision 2.7:
+a.)"Multimedia devices" => "Customise DVB frontends" => "Customise the frontend modules to build"
+b.)"Multimedia devices" => "Customise DVB frontends" => "Samsung S5H1420 based"
+c.)"Multimedia devices" => "Customise DVB frontends" => "Integrant ITD1000 Zero IF tuner for DVB-S/DSS"
+d.)"Multimedia devices" => "Customise DVB frontends" => "ISL6421 SEC controller"
+
+4.) Revision 2.8:
+a.)"Multimedia devices" => "Customise DVB frontends" => "Customise the frontend modules to build"
+b.)"Multimedia devices" => "Customise DVB frontends" => "Conexant CX24113/CX24128 tuner for DVB-S/DSS"

+a.)"Multimedia devices" => "Customise DVB frontends" => "Customise the frontend modules to build"
+b.)"Multimedia devices" => "Customise DVB frontends" => "Zarlink MT352 based"
+
+6.) DVB-C card:

+Overview of the V4L2 driver framework
+=====================================
+
+This text documents the various structures provided by the V4L2 framework and
+their relationships.
+
+
+Introduction
+------------
+
+The V4L2 drivers tend to be very complex due to the complexity of the
+hardware: most devices have multiple ICs, export multiple device nodes in
+/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input
+(IR) devices.
+
+Especially the fact that V4L2 drivers have to setup supporting ICs to
+do audio/video muxing/encoding/decoding makes it more complex than most.
+Usually these ICs are connected to the main bridge driver through one or
+more I2C busses, but other busses can also be used. Such devices are
+called 'sub-devices'.
+
+For a long time the framework was limited to the video_device struct for
+creating V4L device nodes and video_buf for handling the video buffers
+(note that this document does not discuss the video_buf framework).
+
+This meant that all drivers had to do the setup of device instances and
+connecting to sub-devices themselves. Some of this is quite complicated
+to do right and many drivers never did do it correctly.
+
+There is also a lot of common code that could never be refactored due to
+the lack of a framework.
+
+So this framework sets up the basic building blocks that all drivers
+need and this same framework should make it much easier to refactor
+common code into utility functions shared by all drivers.
+
+
+Structure of a driver
+---------------------
+
+All drivers have the following structure:
+
+1) A struct for each device instance containing the device state.
+
+2) A way of initializing and commanding sub-devices (if any).
+
+3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX, /dev/radioX and
+   /dev/vtxX) and keeping track of device-node specific data.
+
+4) Filehandle-specific structs containing per-filehandle data.
+
+This is a rough schematic of how it all relates:
+
+    device instances
+      |
+      +-sub-device instances
+      |
+      \-V4L2 device nodes
+	  |
+	  \-filehandle instances
+
+
+Structure of the framework
+--------------------------
+
+The framework closely resembles the driver structure: it has a v4l2_device
+struct for the device instance data, a v4l2_subdev struct to refer to
+sub-device instances, the video_device struct stores V4L2 device node data
+and in the future a v4l2_fh struct will keep track of filehandle instances
+(this is not yet implemented).
+
+
+struct v4l2_device
+------------------
+
+Each device instance is represented by a struct v4l2_device (v4l2-device.h).
+Very simple devices can just allocate this struct, but most of the time you
+would embed this struct inside a larger struct.
+
+You must register the device instance:
+
+	v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
+
+Registration will initialize the v4l2_device struct and link dev->driver_data
+to v4l2_dev. Registration will also set v4l2_dev->name to a value derived from
+dev (driver name followed by the bus_id, to be precise). You may change the
+name after registration if you want.
+
+You unregister with:
+
+	v4l2_device_unregister(struct v4l2_device *v4l2_dev);
+
+Unregistering will also automatically unregister all subdevs from the device.
+
+Sometimes you need to iterate over all devices registered by a specific
+driver. This is usually the case if multiple device drivers use the same
+hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv
+hardware. The same is true for alsa drivers for example.
+
+You can iterate over all registered devices as follows:
+
+static int callback(struct device *dev, void *p)
+{
+	struct v4l2_device *v4l2_dev = dev_get_drvdata(dev);
+
+	/* test if this device was inited */
+	if (v4l2_dev == NULL)
+		return 0;
+	...
+	return 0;
+}
+
+int iterate(void *p)
+{
+	struct device_driver *drv;
+	int err;
+
+	/* Find driver 'ivtv' on the PCI bus.
+	   pci_bus_type is a global. For USB busses use usb_bus_type. */
+	drv = driver_find("ivtv", &pci_bus_type);
+	/* iterate over all ivtv device instances */
+	err = driver_for_each_device(drv, NULL, p, callback);
+	put_driver(drv);
+	return err;
+}
+
+Sometimes you need to keep a running counter of the device instance. This is
+commonly used to map a device instance to an index of a module option array.
+
+The recommended approach is as follows:
+
+static atomic_t drv_instance = ATOMIC_INIT(0);
+
+static int __devinit drv_probe(struct pci_dev *dev,
+				const struct pci_device_id *pci_id)
+{
+	...
+	state->instance = atomic_inc_return(&drv_instance) - 1;
+}
+
+
+struct v4l2_subdev
+------------------
+
+Many drivers need to communicate with sub-devices. These devices can do all
+sort of tasks, but most commonly they handle audio and/or video muxing,
+encoding or decoding. For webcams common sub-devices are sensors and camera
+controllers.
+
+Usually these are I2C devices, but not necessarily. In order to provide the
+driver with a consistent interface to these sub-devices the v4l2_subdev struct
+(v4l2-subdev.h) was created.
+
+Each sub-device driver must have a v4l2_subdev struct. This struct can be
+stand-alone for simple sub-devices or it might be embedded in a larger struct
+if more state information needs to be stored. Usually there is a low-level
+device struct (e.g. i2c_client) that contains the device data as setup
+by the kernel. It is recommended to store that pointer in the private
+data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go
+from a v4l2_subdev to the actual low-level bus-specific device data.
+
+You also need a way to go from the low-level struct to v4l2_subdev. For the
+common i2c_client struct the i2c_set_clientdata() call is used to store a
+v4l2_subdev pointer, for other busses you may have to use other methods.
+
+From the bridge driver perspective you load the sub-device module and somehow
+obtain the v4l2_subdev pointer. For i2c devices this is easy: you call
+i2c_get_clientdata(). For other busses something similar needs to be done.
+Helper functions exists for sub-devices on an I2C bus that do most of this
+tricky work for you.
+
+Each v4l2_subdev contains function pointers that sub-device drivers can
+implement (or leave NULL if it is not applicable). Since sub-devices can do
+so many different things and you do not want to end up with a huge ops struct
+of which only a handful of ops are commonly implemented, the function pointers
+are sorted according to category and each category has its own ops struct.
+
+The top-level ops struct contains pointers to the category ops structs, which
+may be NULL if the subdev driver does not support anything from that category.
+
+It looks like this:
+
+struct v4l2_subdev_core_ops {
+	int (*g_chip_ident)(struct v4l2_subdev *sd, struct v4l2_chip_ident *chip);
+	int (*log_status)(struct v4l2_subdev *sd);
+	int (*init)(struct v4l2_subdev *sd, u32 val);
+	...
+};
+
+struct v4l2_subdev_tuner_ops {
+	...
+};
+
+struct v4l2_subdev_audio_ops {
+	...
+};
+
+struct v4l2_subdev_video_ops {
+	...
+};
+
+struct v4l2_subdev_ops {
+	const struct v4l2_subdev_core_ops  *core;
+	const struct v4l2_subdev_tuner_ops *tuner;
+	const struct v4l2_subdev_audio_ops *audio;
+	const struct v4l2_subdev_video_ops *video;
+};
+
+The core ops are common to all subdevs, the other categories are implemented
+depending on the sub-device. E.g. a video device is unlikely to support the
+audio ops and vice versa.
+
+This setup limits the number of function pointers while still making it easy
+to add new ops and categories.
+
+A sub-device driver initializes the v4l2_subdev struct using:
+
+	v4l2_subdev_init(subdev, &ops);
+
+Afterwards you need to initialize subdev->name with a unique name and set the
+module owner. This is done for you if you use the i2c helper functions.
+
+A device (bridge) driver needs to register the v4l2_subdev with the
+v4l2_device:
+
+	int err = v4l2_device_register_subdev(device, subdev);
+
+This can fail if the subdev module disappeared before it could be registered.
+After this function was called successfully the subdev->dev field points to
+the v4l2_device.
+
+You can unregister a sub-device using:
+
+	v4l2_device_unregister_subdev(subdev);
+
+Afterwards the subdev module can be unloaded and subdev->dev == NULL.
+
+You can call an ops function either directly:
+
+	err = subdev->ops->core->g_chip_ident(subdev, &chip);
+
+but it is better and easier to use this macro:
+
+	err = v4l2_subdev_call(subdev, core, g_chip_ident, &chip);
+
+The macro will to the right NULL pointer checks and returns -ENODEV if subdev
+is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
+NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
+
+It is also possible to call all or a subset of the sub-devices:
+
+	v4l2_device_call_all(dev, 0, core, g_chip_ident, &chip);
+
+Any subdev that does not support this ops is skipped and error results are
+ignored. If you want to check for errors use this:
+
+	err = v4l2_device_call_until_err(dev, 0, core, g_chip_ident, &chip);
+
+Any error except -ENOIOCTLCMD will exit the loop with that error. If no
+errors (except -ENOIOCTLCMD) occured, then 0 is returned.
+
+The second argument to both calls is a group ID. If 0, then all subdevs are
+called. If non-zero, then only those whose group ID match that value will
+be called. Before a bridge driver registers a subdev it can set subdev->grp_id
+to whatever value it wants (it's 0 by default). This value is owned by the
+bridge driver and the sub-device driver will never modify or use it.
+
+The group ID gives the bridge driver more control how callbacks are called.
+For example, there may be multiple audio chips on a board, each capable of
+changing the volume. But usually only one will actually be used when the
+user want to change the volume. You can set the group ID for that subdev to
+e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
+v4l2_device_call_all(). That ensures that it will only go to the subdev
+that needs it.
+
+The advantage of using v4l2_subdev is that it is a generic struct and does
+not contain any knowledge about the underlying hardware. So a driver might
+contain several subdevs that use an I2C bus, but also a subdev that is
+controlled through GPIO pins. This distinction is only relevant when setting
+up the device, but once the subdev is registered it is completely transparent.
+
+
+I2C sub-device drivers
+----------------------
+
+Since these drivers are so common, special helper functions are available to
+ease the use of these drivers (v4l2-common.h).
+
+The recommended method of adding v4l2_subdev support to an I2C driver is to
+embed the v4l2_subdev struct into the state struct that is created for each
+I2C device instance. Very simple devices have no state struct and in that case
+you can just create a v4l2_subdev directly.
+
+A typical state struct would look like this (where 'chipname' is replaced by
+the name of the chip):
+
+struct chipname_state {
+	struct v4l2_subdev sd;
+	...  /* additional state fields */
+};
+
+Initialize the v4l2_subdev struct as follows:
+
+	v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
+
+This function will fill in all the fields of v4l2_subdev and ensure that the
+v4l2_subdev and i2c_client both point to one another.
+
+You should also add a helper inline function to go from a v4l2_subdev pointer
+to a chipname_state struct:
+
+static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
+{
+	return container_of(sd, struct chipname_state, sd);
+}
+
+Use this to go from the v4l2_subdev struct to the i2c_client struct:
+
+	struct i2c_client *client = v4l2_get_subdevdata(sd);
+
+And this to go from an i2c_client to a v4l2_subdev struct:
+
+	struct v4l2_subdev *sd = i2c_get_clientdata(client);
+
+Finally you need to make a command function to make driver->command()
+call the right subdev_ops functions:
+
+static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
+{
+	return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);
+}
+
+If driver->command is never used then you can leave this out. Eventually the
+driver->command usage should be removed from v4l.
+
+Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
+is called. This will unregister the sub-device from the bridge driver. It is
+safe to call this even if the sub-device was never registered.
+
+
+The bridge driver also has some helper functions it can use:
+
+struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
+
+This loads the given module (can be NULL if no module needs to be loaded) and
+calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
+If all goes well, then it registers the subdev with the v4l2_device. It gets
+the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
+that adapdata is set to v4l2_device when you setup the i2c_adapter in your
+driver.
+
+You can also use v4l2_i2c_new_probed_subdev() which is very similar to
+v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses
+that it should probe. Internally it calls i2c_new_probed_device().
+
+Both functions return NULL if something went wrong.

+   Usually these devices are controlled through an i2c bus, but other busses

+   limited set (no more than approx. 8 categories).
+
+   Each category has its own set of ops that subdev drivers can implement.
+
+   A subdev driver can leave the pointer to the category ops NULL if
+   it does not implement them (e.g. an audio subdev will generally not
+   implement the video category ops). The exception is the core category:

From 5ea9c4def8154a5be836dd31cbd97f49fd34ea8f Mon Sep 17 00:00:00 2001
From: Jim Paris <jim@jtan.com>
Date: Thu, 4 Dec 2008 04:36:14 -0300
Subject: [PATCH 369/583] V4L/DVB (9859): gspca - ov534: Fix frame size so we
 don't miss the last pixel.

The frame size is too small, so we lose the last YUYV pixel.
Fix the setup and remove the last_pixel hack.

Subject: [PATCH 370/583] V4L/DVB (9860): gspca - ov534: Frame transfer
 improvements.

The indirect registers at 0x1c/0x1d control frame settings.  If we
leave the values at 0x0a and 0x0b at their reset-time defaults, frame
data from the camera matches the UVC payload format.  This lets us
better reassemble the data into frames and know when data was lost.

This also lets us relax the bulk_size requirement from 600K to 2K,
which should help systems on with limited RAM (like the PS3).

Subject: [PATCH 382/583] V4L/DVB (9874): gspca - ov534: Explicitly initialize
 frame format.

Set frame format registers 0x0a and 0x0b to explicit values
rather than relying on reset-time defaults.

Subject: [PATCH 383/583] V4L/DVB (9876): gspca - main: Allow subdrivers to
 handle v4l2_streamparm requests.

Add get_streamparm and set_streamparm operations so subdrivers can
get/set stream parameters such as framerate.

cx18: Use a known open task handle when setting stream CX2341x parameters
Sometimes, we might only have VBI or YUV stream open instead of an MPEG stream.
Let's make sure we use a valid task handle to perform the CX2341x control
settings.

Subject: [PATCH 399/583] V4L/DVB (9897): v4l2: Add camera zoom controls

The zoom controls move the zoom lens group to a an absolute position, as a
relative displacement or at a given speed until reaching physical device
limits. Positive values move the zoom lens group towards the telephoto
direction, negative values towards the wide-angle direction.

Subject: [PATCH 400/583] V4L/DVB (9898): v4l2: Add privacy control

The privacy control prevents video from being acquired by the camera. A true
value indicates that no image can be captured. Devices that implement the
privacy control must support read access and may support write access.

Subject: [PATCH 408/583] V4L/DVB (9911): em28xx: vidioc_try_fmt_vid_cap()
 doesn't need any lock

vidioc_try_fmt_vid_cap() just checks if a given resolution is supported.
It doesn't touch on struct em28xx device descriptor. so, there's no need
to lock.

While there, use unlikely() for those values that aren't likely to
occur.

 schema

Changes/fixes on em28xx dev->lock:

- em28xx_init_dev() were unlocking without a previous lock;

- some read ioctls need to lock after the removal of KBL, since a write
  may be happening at the same time an ioctl is reading;

- keep the device locked during all device initialization;

- lock/unlock while reading/writing registers.

Subject: [PATCH 410/583] V4L/DVB (9913): tuner-xc2028: allow printing stack
 trace as debug on sleep code

tuner-xc3028 can be put to sleep to save power. However, if not properly
recovered from sleep, the device won't work. It is noticed that some
devices doesn't recover properly, so let's add a dump_stack() as a debug
option, to allow us to track when this happens.

It has been noticed that in HW tuning mode in cx24123.c that
a check is made to not alter the status var when in one shot
mode, a simpler solution is to not update here for all cards.

Appears to be resolved by dropping zig-zag tuning and relying on
hardware only:

> szap-s2 -r -c 39.FTATV "1=Pgm1;Net1"
reading channels from file '39.FTATV'
zapping to 3 '1=Pgm1;Net1':

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

status 1f | signal ff80 | snr c199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Tuning to a weaker channel shows that the hardware recovers sync:

status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fd40 | snr 5000 | ber 00000000 | unc 00000000 |

status 01 | signal fd80 | snr 4e66 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 03 | signal fe40 | snr 5000 | ber 00000000 | unc 00000000 |
status 01 | signal fd80 | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal fe40 | snr 5199 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Also, tuning, moving the dish and then restoring the dish also retunes.

This cleans-up the advise/acquire methods.

This has been tested on the hvr-1300/4000 and assumed to be
correct on the hvr-3000.

This update also fixes analogue tuning on the hvr-1300
when in blackbird mode.

Subject: [PATCH 417/583] V4L/DVB (9922): em28xx: don't assume every eb1a:2820
 reference design is a Prolink PlayTV USB2

Don't operate under the assumption that every device that uses the em2820
default USB ID is a Prolink PlayTV USB.  We have an eeprom hash, so use that,
since otherwise we cannot support other devices with the 2820 default USB ID
(such as the ADS Tech Instant TV USB USBAV-704)

Subject: [PATCH 418/583] V4L/DVB (9923): xc5000: remove init_fw option

The init_fw option was broken for the HVR-950q because we would call the reset
callback inside of dvb_attach() and the callback had not been setup yet.

Michael Krufky (who added the init_fw feature) says it's no longer required,
so just remove the option completely.

Thanks to user Zzeiss from #linuxtv chat for reporting the issue and
Michael Krufky <mkrufky@linuxtv.org> for proposing the fix.

 xc2028/3028 tuner to sleep

The changeset 78aa52a159cf introduced a bug on em28xx: buffer setup should be
awaking xc3028. Instead, since we didn't specify the tuner mode, the device
were going to sleep, due to the lack of tuner mode when asking tuner to handle
VIDIOC_S_FREQUENCY:

xc2028 0-0061: Device is Xceive 3028 version 1.0, firmware version 2.7
xc2028 0-0061: divisor= 00 00 14 d0 (freq=83.250)

Subject: [PATCH 422/583] V4L/DVB (9928): Convert GP8PSK module to use S2API

This patch converts the gp8psk module to use the S2API.
It pretends to be  DVB-S2 capable in order to allow the various
supported modulations (8PSK, QPSK-Turbo, etc), and keep software
compatibility with the S2API patches for Mythtv and VDR.

Subject: [PATCH 427/583] V4L/DVB (9936): cx18: Disable locking of Video and
 Audio PLL for analog captures

Disable AV_LOCK, locking of audio PLL to video PLL in the cx18-av-core for
analog captures.  It seems to have adverse effects on captures from

Subject: [PATCH 428/583] V4L/DVB (9937): cx18: Use a consistent crystal value
 for computing all PLL parameters

Use a consistent crystal value of 28.636360 MHz for computing all PLL
parameters so clocks don't have relative error due to assumed crystal
value mismatches.  Also aimed to have all PLLs run their VOCs at close to
400 MHz to minimze the error of these PLLs as frequency synthesizers. Also
set the VDCLK and AIMCLK PLLs to sane values before the APU and CPU firmware
are loaded.  Also fixed I2S Master clock dividers.

Many thanks to Mike Bradley and Jeff Campbell for reporting this problem and
suggesting the solution, researching and experimenting, and performing
extensive testing to support their suggested solution.

- Video Sampling
-Digital video is a sampled form of analog video. The most common sampling schemes in use today are:
-		  Pixel Clock   Horiz    Horiz    Vert
-		   Rate         Total    Active
-NTSC square pixel  12.27 MHz    780      640      525
-NTSC CCIR-601      13.5  MHz    858      720      525
-NTSC 4FSc          14.32 MHz    910      768      525
-PAL  square pixel  14.75 MHz    944      768      625
-PAL  CCIR-601      13.5  MHz    864      720      625
-PAL  4FSc          17.72 MHz   1135      948      625
-
-For the CCIR-601 standards, the sampling is based on a static orthogonal sampling grid. The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync. The samples are coded to either 8 or 10 bits per component.

+video_device struct (v4l2-dev.h). This struct can either be allocated
+dynamically or embedded in a larger struct.
+
+To allocate it dynamically use:
+
+	struct video_device *vdev = video_device_alloc();
+
+	if (vdev == NULL)
+		return -ENOMEM;
+
+	vdev->release = video_device_release;
+
+If you embed it in a larger struct, then you must set the release()
+callback to your own function:
+
+	struct video_device *vdev = &my_vdev->vdev;
+
+	vdev->release = my_vdev_release;
+
+The release callback must be set and it is called when the last user
+of the video device exits.
+
+The default video_device_release() callback just calls kfree to free the
+allocated memory.
+
+You should also set these fields:
+
+- parent: set to the parent device (same device as was used to register
+  v4l2_device).
+- name: set to something descriptive and unique.
+- fops: set to the file_operations struct.
+- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
+  (highly recommended to use this and it might become compulsory in the
+  future!), then set this to your v4l2_ioctl_ops struct.
+
+If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to
+__video_ioctl2 or .ioctl to video_ioctl2 in your file_operations struct.
+
+
+video_device registration
+-------------------------
+
+Next you register the video device: this will create the character device
+for you.
+
+	err = video_register_device(vdev, VFL_TYPE_GRABBER, -1);
+	if (err) {
+		video_device_release(vdev); // or kfree(my_vdev);
+		return err;
+	}
+
+Which device is registered depends on the type argument. The following
+types exist:
+
+VFL_TYPE_GRABBER: videoX for video input/output devices
+VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext)
+VFL_TYPE_RADIO: radioX for radio tuners
+VFL_TYPE_VTX: vtxX for teletext devices (deprecated, don't use)
+
+The last argument gives you a certain amount of control over the device
+kernel number used (i.e. the X in videoX). Normally you will pass -1 to
+let the v4l2 framework pick the first free number. But if a driver creates
+many devices, then it can be useful to have different video devices in
+separate ranges. For example, video capture devices start at 0, video
+output devices start at 16.
+
+So you can use the last argument to specify a minimum kernel number and
+the v4l2 framework will try to pick the first free number that is equal
+or higher to what you passed. If that fails, then it will just pick the
+first free number.
+
+Whenever a device node is created some attributes are also created for you.
+If you look in /sys/class/video4linux you see the devices. Go into e.g.
+video0 and you will see 'name' and 'index' attributes. The 'name' attribute
+is the 'name' field of the video_device struct. The 'index' attribute is
+a device node index that can be assigned by the driver, or that is calculated
+for you.
+
+If you call video_register_device(), then the index is just increased by
+1 for each device node you register. The first video device node you register
+always starts off with 0.
+
+Alternatively you can call video_register_device_index() which is identical
+to video_register_device(), but with an extra index argument. Here you can
+pass a specific index value (between 0 and 31) that should be used.
+
+Users can setup udev rules that utilize the index attribute to make fancy
+device names (e.g. 'mpegX' for MPEG video capture device nodes).
+
+After the device was successfully registered, then you can use these fields:
+
+- vfl_type: the device type passed to video_register_device.
+- minor: the assigned device minor number.
+- num: the device kernel number (i.e. the X in videoX).
+- index: the device index number (calculated or set explicitly using
+  video_register_device_index).
+
+If the registration failed, then you need to call video_device_release()
+to free the allocated video_device struct, or free your own struct if the
+video_device was embedded in it. The vdev->release() callback will never
+be called if the registration failed, nor should you ever attempt to
+unregister the device if the registration failed.
+
+
+video_device cleanup
+--------------------
+
+When the video device nodes have to be removed, either during the unload
+of the driver or because the USB device was disconnected, then you should
+unregister them:
+
+	video_unregister_device(vdev);
+
+This will remove the device nodes from sysfs (causing udev to remove them
+from /dev).
+
+After video_unregister_device() returns no new opens can be done.
+
+However, in the case of USB devices some application might still have one
+of these device nodes open. You should block all new accesses to read,
+write, poll, etc. except possibly for certain ioctl operations like
+queueing buffers.
+
+When the last user of the video device node exits, then the vdev->release()
+callback is called and you can do the final cleanup there.
+
+
+video_device helper functions
+-----------------------------
+
+There are a few useful helper functions:
+
+You can set/get driver private data in the video_device struct using:
+
+void *video_get_drvdata(struct video_device *dev);
+void video_set_drvdata(struct video_device *dev, void *data);
+
+Note that you can safely call video_set_drvdata() before calling
+video_register_device().
+
+And this function:
+
+struct video_device *video_devdata(struct file *file);
+
+returns the video_device belonging to the file struct.
+
+The final helper function combines video_get_drvdata with
+video_devdata:
+
+void *video_drvdata(struct file *file);
+
+You can go from a video_device struct to the v4l2_device struct using:
+
+struct v4l2_device *v4l2_dev = dev_get_drvdata(vdev->parent);
+

From b3ee7e21f25cdd50cccc906dc09e547f36166372 Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Fri, 19 Dec 2008 10:34:22 -0300
Subject: [PATCH 446/583] V4L/DVB (9967): cs5345: convert to v4l2_subdev and
 fix broken s_ctrl.

Converted to v4l2_subdev. While doing that I also discovered a stray 'break'
that broke the S_CTRL handling. Fixed that as well.

Subject: [PATCH 450/583] V4L/DVB (9973): v4l2-dev: use the release callback
 from device instead of cdev

Instead of relying on the cdev release callback we should rely on the
release callback from the device struct. This requires that we use
get_device/put_device to do proper refcounting. In order to do this
safely v4l2-dev.c now sets up its own file_operations that call
out to the driver's ops.

Subject: [PATCH 451/583] V4L/DVB (9974): v4l2-dev: allow drivers to pass
 v4l2_device as parent

Drivers that use v4l2_device can set that as parent pointer in the v4l2_dev
field instead of using the struct device parent field.

This allows v4l2-dev.c to check whether this driver is v4l2_device based,
and if so then it can offer additional services.

Subject: [PATCH 455/583] V4L/DVB (9979): em28xx: move usb probe code to a
 proper place

em28xx-video were holding several code that are not specific to V4L2
interface.

This patch moves the core code for em28xx-core, and usb probing code
into em28xx-cards.

This opens the possibility of breaking em28xx into a core module and a
V4L2 module, loaded only on devices that have analog interfaces.

Subject: [PATCH 456/583] V4L/DVB (9980): em28xx: simplify analog logic

Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.

After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on analog devices.

Subject: [PATCH 518/583] V4L/DVB (10053): radio-mr800: disable autosuspend
 support

Because this device doesn't provide any powermanagment capabilities(may
be they exist but unknown to me yet, so they are not implemented), we
should turn them off. Patch sets support_autosuspend equal to 0.

Subject: [PATCH 523/583] V4L/DVB (10058): dsbr100: fix codingstyle, add
 dev_err messages

We should make if-constructions more clear. Introduce int retval
variables in some functions to make it this way. Also a lot of useful
dev_err messages added. And now we check every returned value after
usb_control_msg.

Subject: [PATCH 537/583] V4L/DVB (10072): soc-camera: Add signal inversion
 flags to be used by camera drivers

As reported by Antonio Ospite <ospite@studenti.unina.it> two platforms with a
mt9m111 camera require opposite pixel clock polarity, which means one of them
inverts it. This patch adds support for inversion flags and switches all
available camera drivers to using them.

Subject: [PATCH 539/583] V4L/DVB (10074): soc-camera: add camera sense data

Add a struct soc_camera_sense, that can be used by camera host drivers to
request additional information from a camera driver, for example, when
changing data format. This struct can be extended in the future, its first use
is to request the camera driver whether the pixel-clock frequency has changed.

Subject: [PATCH 540/583] V4L/DVB (10075): pxa-camera: setup the FIFO
 inactivity time-out register

Using PXA270's FIFO inactivity time-out register (CITOR) reduces FIFO overruns.
The time-out is calculated in CICLK / LCDCLK ticks and has to be longer than
one pixel time. For this we have to know the pixel clock frequency, which
usually is provided by the camera. We use the struct soc_camera_sense to
request PCLK frequency from the camera driver upon each data format change.

Subject: [PATCH 543/583] V4L/DVB (10078): video: add NV16 and NV61 pixel
 formats

This patch adds support for NV16 and NV61 pixel formats.

These pixel formats use two planes; one for 8-bit Y values and
one for interleaved 8-bit U and V values. NV16/NV61 formats are
very similar to NV12/NV21 with the exception that NV16/NV61 are
using the same number of lines for both planes. The difference
between NV16 and NV61 is the U and V byte order.

The fourcc values are extrapolated from the NV12/NV21 case.

Subject: [PATCH 546/583] V4L/DVB (10081): pxa-camera: call try_fmt() camera
 device method with correct pixel format

With the introduction of the format conversion support in soc-camera, we now
also have to take care to pass the correct pixel format to the camera driver
when calling its try_fmt() method.

Subject: [PATCH 554/583] V4L/DVB (10090): soc-camera: let drivers decide upon
 supported field values

sh_mobile_ceu_camera.c is already prepared to support interlaced format, this
patch moves the choice of a field type down to host and / or camera drivers.

Subject: [PATCH 559/583] V4L/DVB (10095): The failure of set_fmt is solved in
 tw9910

priv->scale is checked in start_capture.
Therefore, it should be NULL if failing in set_fmt.
This patch resolve this problem.

Subject: [PATCH 563/583] V4L/DVB (10099): soc-camera: add support for MT9T031
 CMOS camera sensor from Micron

This camera is rather similar to MT9M001, but also has a couple of
enhanced features, like pixel binning.

Subject: [PATCH 564/583] V4L/DVB (10101): uvcvideo: Fix bulk URB processing
 when the header is erroneous

When the first bulk URB of a video payload contains an erroneous header, or
when no V4L2 buffer is available, the whole payload must be dropped. Change
the skip logic to drop all bulk URBs until the end of the payload instead of
the first one only.

 function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

drivers/media/dvb/dvb-usb/anysee.c: In function ‘anysee_master_xfer’:
drivers/media/dvb/dvb-usb/anysee.c:156: warning: ‘ret’ may be used uninitialized

By looking at the function, altrough very unlikely, this might
eventually be true if num  = 0. So, better to fix the warning by
initializing with ret = 0.

Subject: [PATCH 568/583] V4L/DVB (10110): v4l2-ioctl: Fix warnings when using
 .unlocked_ioctl = __video_ioctl2

This patch fixes this warning:

drivers/media/video/gspca/gspca.c:1811: warning: initialization from incompatible pointer type

The reason is that the returned argument should be a long, not an
integer.

Subject: [PATCH 573/583] V4L/DVB (10119): em28xx: fix corrupted XCLK value

Correct problem introduced during the board refactoring where the XCLK
frequency would get zero'd out.  The sequence of events was as follows:

em28xx_pre_card_setup() called em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration
em28xx_pre_card_setup() would set the dev->board.xclk if not set
em28xx_pre_card_setup() would set the XCLK register based on dev->board.xclk
...
em28xx_card_setup() would call em28xx_set_model()
em28xx_set_model() would memcpy to dev->board configuration (clearing out
 value of dev->board.xclk set in em28xx_pre_card_setup)
...
em28xx_audio_analog_set() sets the XCLK register based on dev->board.xclk
 (which now contains zero)

The change sets the default XCLK and I2C Clock fields in the board definition
inside of em28xx_set_model() so that subsequent calls do not cause the
values to be overwritten.

 PCTV HD Mini 80e device profile

The Pinnacle 80e cannot be supported since Micronas yanked their driver
support for the drx-j chipset at the last minute.  Remove the device profile
since it cannot work without the drx driver and it being there is only likely
to confuse people into thinking the device is supported but not working.

The current code was trying to query the AC97 registers for the vendor
information even if it was clearly not a AC97 audio device (resulting in errors
in the dmesg output).  This was due to a bug in the way we did the check.

 RW_LOCK_UNLOCKED in frontends

Impact: clean up

RW_LOCK_UNLOCKED is deprecated.  This patch replaces it with the
__RW_LOCK_UNLOCKED(lock) macro.  This change was a little trickier than
others due to the macro being used in another macro that fills an array.

Subject: [PATCH 583/583] V4L/DVB (10130): use USB API functions rather than
 constants

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_is_isoc_in(epd)
usb_endpoint_is_isoc_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r1@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) ==
- \(USB_ENDPOINT_XFER_CONTROL\|0\))
+ usb_endpoint_xfer_control(epd)

@r5@ struct usb_endpoint_descriptor *epd; @@

- ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) ==
-  \(USB_DIR_IN\|0x80\))
+ usb_endpoint_dir_in(epd)
