Genpix is demodulating DVB-S-like signal with 8PSK modulation used) -
this non-standard behaviour was broken by rejecting 8PSK in a standard
DVB-S tune request. This problem is fixed by simply reverting back to

This patch adds a fix to accept frequency with its center shifted.
The driver used to accept center frequencies of the normal UHF band channels,
but in ISDB-T, center frequency is shifted with 1/7MHz.
It was shifted internally in the driver,
but this patch enables to accept both types of frequency.

This device uses an i2c chip to retrieve the keycode from a RC5 remote.
Instead of just getting 6 bits, improve the routine to get 11 bits.
This means that the complete RC5 table for Hauppauge Grey IR can be used
with this device.
Unfortunately, it seems that this IR receiver is not capable of getting
the full 14 (or 13 bits) from the RC5 protocol.
At lest now, with the new code, it is possible to replace this IR table
by another RC5 table.

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.

The video_device::minor field is used where it shouldn't, either to
- test for error conditions that can't happen anymore with the current
v4l-dvb core,
- store the value in a driver private field that isn't used anymore,
- check the video device type where video_device::vfl_type should be
used, or
- create the name of a kernel thread that should get a stable name.
Remove or fix those use cases.
