cd7d9beb09 V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late
v4l2_device_register needs to be called before the i2c subdevs are loaded.
However, it was called afterwards in the saa7146 driver. This caused an oops
when loading the mxb and hexium drivers. The vv_init function is now split
into two: one registers the v4l2_device, the other does the rest of the
initialization. The three drivers that depend on this have been updated to
call the new vv_devinit function.

Thanks to Michael Hunold for reporting this.

3ccc646b56 V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audio
This change attempts to fix the ivtv tinny audio problem by keeping digitizer
to encoder audio clocks running, while disabling the video clocks as needed to
avoid unpredictable PCI bus hangs.

To accomplish this, for the cx25840 module enabling of audio streaming had
to be separated from enabling video streaming, requiring an additional
v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers.

The cx231xx and cx23885 driver use the cx25840 module for affecting only
video on s_stream calls, so those drivers needed no change.

The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI
bus hang, so the cx18 driver did not need corresponding changes.

CX2341[56] based cards that are not using the CX2584x family of chips
do not seem to be affected by the tinny audio problem, and this change should
not affect how they are configured. It will delay their first capture by
starting by another 300 msec though.

Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and
Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and
investigation of this problem will hopefully fix this problem once and for all
for many ivtv users.

9a74251d8b V4L/DVB (13658): v4l: add a media-bus API for configuring v4l2 subdev pixel and frame formats
Video subdevices, like cameras, decoders, connect to video bridges over
specialised busses. Data is being transferred over these busses in various
formats, which only loosely correspond to fourcc codes, describing how video
data is stored in RAM. This is not a one-to-one correspondence, therefore we
cannot use fourcc codes to configure subdevice output data formats. This patch
adds codes for several such on-the-bus formats and an API, similar to the
familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those
codes. After all users of the old API in struct v4l2_subdev_video_ops are
converted, it will be removed. Also add helper routines to support generic
pass-through mode for the soc-camera framework.

b6456c0cfe V4L/DVB (13571): v4l: Adding Digital Video Timings APIs
This adds the above APIs to the v4l2 core. This is based on version v1.2
of the RFC titled "V4L - Support for video timings at the input/output interface"
Following new ioctls are added:-

        - VIDIOC_ENUM_DV_PRESETS
        - VIDIOC_S_DV_PRESET
        - VIDIOC_G_DV_PRESET
        - VIDIOC_QUERY_DV_PRESET
        - VIDIOC_S_DV_TIMINGS
        - VIDIOC_G_DV_TIMINGS

Please refer to the RFC for the details. This code was tested using vpfe
capture driver on TI's DM365. Following is the test configuration used :-

Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR

A draft version of the TVP7002 driver (currently being reviewed in the mailing
list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets.

A loopback video capture application was used for testing these APIs. This calls
following IOCTLS :-

 -  verify the new v4l2_input capabilities flag added
 -  Enumerate available presets using VIDIOC_ENUM_DV_PRESETS
 -  Set one of the supported preset using VIDIOC_S_DV_PRESET
 -  Get current preset using VIDIOC_G_DV_PRESET
 -  Detect current preset using VIDIOC_QUERY_DV_PRESET
 -  Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS
    and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device.
 -  Tested on 64bit platform by Hans Verkuil

cda4303f55 V4L/DVB (13546): ir-keymaps: Add table for Terratec Cinergy XS FM
This IR uses NEC protocol, with address=0x14. This keymap is similar
to the existing Terratec Cinergy XS, except that:
	- it contains the full address/command code;
	- the Music button were mapped as KEY_RADIO;
	- some keycodes from the previous entry were wrong, IMHO.

While here, convert the protocol types into an enum
and define 0 as unknown.

7fee03e487 V4L/DVB (13540): ir-common: Cleanup get key evdev code
The same loop to seek for a key were used on different places. Also,
no spinlock were protecting it to avoid the risk of replacing a keycode
while seeking for a new code.

This cleanup does:
	- create an unique function to seek for a code;
	- adds an spinlock to protect the table lookup;
	- remove some unused code;
	- simplifies to code to make it easier to understand.

Basically no change in behavior should be noticed after this patch.

055cd55601 V4L/DVB (13537): ir: Prepare the code for dynamic keycode table allocation
Currently, the IR table is initialized by calling ir_input_init(). However,
this function doesn't return any error code, nor has a function to be called
when de-initializing the IR's.

Change the return argment to integer and make sure that each driver will
handle the error code. Also adds a function to free any resources that may
be allocating there: ir_input_free().

Now that V4L drivers can support more than 7 bits for scan code, let's
add a modified version for the Hauppauge Grey IR containing the full IR
scancode.
