This change fixes up saa7127_s_std() generate SECAM out, if the user has
requested a 50 Hz video standard set that only contains a request for SECAM
standards and not PAL. Only the SAA712[89] chips can generate SECAM, the
SAA712[67] chips cannot.
I was unclear on the burst start and end values - I couldn't figure out
the units - so I left them the same as for the PAL systems.
A the video decoders on both a PVR-350 (SAA7115) and an HVR-1600 (CX23418)
identify the SECAM signal generated by a SAA7129 with this patch as SECAM.

Fix the "xceive_pin" setting from "15" to "1" for the PVR2100 -- the same as
the PVR3100H. This properly resets the XC2028 tuner on the PVR2100.
Sergey's original email report:
Hi.
Seems cx18 module has incorrect .xceive_pin value for card,
as i see lots of i2c errors in dmesg from xc2028.
i'm using 2.6.32.2, my hardware is:

VIDIOC_G_ENC_INDEX support see the light of day.
Some notes:
1. With default capture parameters, the CX23418 seems to transfer 192 index
entries (4.5 kB worth) at 10 second intervals.
2. Index streams don't seem to be supported for MPEG 2 TS streams
3. The index entries seem to claim every frame is a B-Frame. Possible
firmware bug.
4. The cx18 driver does not try to capture an index stream when inserting
sliced VBI into the MPEg stream as the offsets would need fixup.

According to the v4l2 spec, very old MPEG index entries needs to be discarded
in favor of newer index entries. This change ensures the firmware always has
buffers for index entries at the expense of the oldest unread buffers.

This change starts the IDX stream along with the MPG stream as an internal
use (only) stream much like the VBI stream can be started as an internal use
stream for inserting sliced VBI packets.
The IDX stream is not started automatically with an MPEG strem if the IDX
stream is disabled (no buffers allocated) or if sliced VBI insertion is being
performed by the cx18 driver. The cx18 driver doing sliced VBI insertion
makes the offsets in the IDX stream inaccurate for the final MPEG stream
presented to user space. Since fixing the IDX offsets ourselves is not easy
and we cannot easily do what ivtv does to fix the offsets, we'll make sliced
VBI insertion and MPEG Index capture mutually exclusive for now.

This change allows the IDX stream to be started and stopped as any other
stream even though it has no associated device node. This is needed for
cx18 driver internal use.
Also always tell the CX23418 to generate index entries when an analog capture
starts and the IDX stream has had buffers allocated (i.e. is enabled).

Update the module options related to INDEX stream buffer allocation. A single
CX2341[5678] index entry is only 24 bytes. Large buffers for the IDX stream
will prevent the CX23418 from transferring index data over at all. Buffers
of around 1.5 kB or 64 index entries seem to be just fine. We'll default to
63 buffers/MDLs as that is the firmware limit per stream and IDX stream buffers
are not high rate. There is no reason on earth to allocate the previous 1 MB
default of buffer space for the IDX stream.
This is in anticipation of implementing the G_ENC_INDEX ioctl() in the cx18
driver.

After taking a look at the driver's history and doing some tests with

ISDB-T, and weren't working for DVB.
Fixed the code and added a debug code to print the complete stats at
dmesg. This debug is useful to improve the stats of this driver.

Based on a patch originally written by Michael Krufky <mkrufky@linuxtv.org>
for a preliminar S2API spec.
The patch were ported to the S2API and had the ISDB-T API additions to
honor the auto mode, while keep allowing manual tuning.
Tested with both the original dvb-apps and the new dvb-apps-isdbt scan,
that uses a different channel.conf and uses S2API with ISDB-T extensions.
