8ccdf1ae9d [media] v4l/dvb: add support for AVerMedia AVerTV Red HD+ (A850T)
The AVerTV Red HD+ (A850T) is basically the same as the existing
AVerTV Volar Black HD (A850), but is specific to the french market.
The A850T identifies itself as a A850, but has its own PID. It even
suffers from the same EEPROM deficiencies.

This is based off a collection of information gathered from the
french support forums for Ubuntu, which I tried to properly format
into this patch:

bae94dc39e [media] cx231xx-417: Fix a gcc warning

drivers/media/video/cx231xx/cx231xx-417.c:1063: warning: operation on ‘i’ may be undefined

Btw, I agree with gcc, as we're using i and i++ at the same operation and,
depending on how optimization may occur, it may produce a wrong code.

While here, fix CodingStyle issues on the changed code.

e350d44fed [media] tda18271: allow restricting max out to 4 bytes
By default, tda18271 tries to optimize I2C bus by updating all registers
at the same time. Unfortunately, some devices doesn't support it.

The current logic has a problem when small_i2c is equal to 8, since there
are some transfers using 11 + 1 bytes.

Fix the problem by enforcing the max size at the right place, and allows
reducing it to max = 3 + 1.

developer adding new boards only needs to specify which tuner the device has.

Of course, the first time somebody adds a board with a tuner other than xc5000
or tda18271, he/she will need to add another line for that tuner.  But we
provide a friendly message in dmesg to let them know that.

at runtime (an abuse of the API).  If this sort of functionality is actually
needed (aside from the existing "transfer_mode" modprobe variable), a patch
can be submitted which makes use of a private control.

b88ba6193d [media] cx231xx: Set the power mode instead of using the digital mux GPIOs
The Exeter hardware design does not use GPIOs to manage whether its in
digital mode or analog mode, but we need to setup the power control properly.

For that board, setup power control and remove the mux select call.  It is
highly likely that this change could be used by other boards as well, which
would make power management cleaner (fixing known issues transitioning between
analog and digital mode).

6e6a2ba9cf [media] cx231xx: do not call video_mux as part of isoc setup
You cannot call the video_mux routine from within the isoc setup, because that
code is shared with the digital isoc handler.  This was causing the GPIOs and
power control to be put into the wrong state when starting up digital mode.

cc355753e8 [media] cx231xx: Clear avmode bits before setting
We need to clear out the field before setting individual bits, or else we end
up with a union of whatever was there and what we are trying to set.  For
example, switching to digital mode ends up being 0x30 instead of 0x10 if we
were previously in analog tv mode.

435b4f7897 [media] cx231xx: make video scaler work properly
Move the responsibility for setting up the horizontal and vertical scalers
entirely to the cx25840 driver.  The cx231xx-avcore was actually programming
garbage into the HSCALE_CTRL and VSCALE_CTRL registers (because of differences
in how the em28xx driver worked, which the cx231xx driver was derived from).

The net effect is that the scaler now works properly (tested with both PAL
and NTSC under mplayer and tvtime).

This patch also gets rid of cx25840 errors showing up in dmesg which say
"720x480 is not a valid size" (since we now properly setup the size of the
active video area).

e3e0aaaafa [media] cx231xx: remove board specific initialization
There is no need for a switch statement here.  Use the contents of the board
profile to dictate the tuner driver and i2c address.  Eventually if a board
ever comes around which has a different i2c bus than #1, well that should be a
field in the board profile as well.

99d35a0e4c [media] cx231xx: Ensure VBI fields are sent in the correct order
The current code was sending one videobuf per field (despite having specified
V4L2_FIELD_SEQ_TB during setup).  As a result, application which used the
read() interface would work, except they would sometimes have the fields
reversed (depending on the luck of which field the device was on when the
application started VBI capture).  The net effect was that CC decoding would
only work about 50% of the time.

Restructure the VBI code a bit so that works like all the other drivers, such
that both fields are delivered in a single videobuf buffer, which ensures that
they are always received in a predictable order.
