[media] V4L-DVB: tm6000: Move VBI init to a separate function
While here, documment that VBI may need changes, based on video STD, and
do some cleanup at device init, to be sure that VBI init will happen
all the times, and to remove a duplicated video standard call.
Instead of doing its own lock, use core-assisted one. As a bonus, it
will do the proper unlock during queue wait events. This fixes a
long-standing bug where softwares like tvtime would hang if you try to
use cx231xx-alsa.

Adjust the vblank and vactive counts so that they don't throw an error in
cx25840's set_std call (we did an equivalent change for NTSC when we got the
scaler working).
[media] cx231xx: properly set active line count for PAL/SECAM
The cx231xx_do_mode_ctrl_overrides() function was not touching the vactive line
count for PAL/SECAM modes, which in some use cases results in it being left in
the chip default state of 480 (NTSC).
Explicitly set the values, as is already done for NTSC.
[media] cx231xx: remove board specific check for Colibri configuration
The cx231xx_set_Colibri_For_LowIF() function is only ever called if the tuner
has a DIF (see vidioc_s_frequency() in cx231xx-video.c). Hence, we do not
need to do a board specific check in this function.
[media] cx231xx: Make the DIF configuration based on the tuner not the board id
The current code was deciding whether a DIF was present based on the board
profile. However, this is just another thing for someone to get wrong when
adding new boards. Make the decision based on the tuner instead, so that a
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.
Nobody is ever going to implement an i2c based IR controller on a bridge that
has an onboard universal IR receiver. This stuff was all copied from em28xx,
which has old enough versions of the chip that some didn't have onboard IR.
Remove the stubs related to i2c based IR (keeping the cx231xx-input code).
[media] cx231xx: make output mode configurable via the board profile
Extend the board profile structure to allow configuration of the output mode.
Right now they are all doing VIP 1.1 format, but we have a board that needs
ITU656 format (which hasn't been checked in yet).
[media] cx231xx: Add initial support for Hauppauge USB-Live2
Add initial support for the Hauppauge USBLive 2 (2040:c200). Note that I
had to copy a bunch of the case statements used for the Conexant video grabber
reference design (which also doesn't have a tuner). This will likely need to
be refactored out into the board profile.
[media] cx231xx: set correct i2c port for Exeter tuner
The tuner is on i2c port 3 just like all the reference designs. Having it
improperly set to port #1 causes the tuner initialization to fail when enabling
the device.
[media] cx231xx: set standard tune to last known frequency when switching inputs
If switching to a tuner input, reset the standard and tune to the last known
frequency. We need to do this in particular for this bridge since the tuner
gets powered down when captuing on the composite or s-video inputs.
[media] cx231xx: Remove hack which puts device into bulk mode
Remove a hack which was jammed into s_input to force the device into bulk mode
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.
[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).
[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.
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.
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).
[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.
[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.
[media] Use smaller i2c transaction size with 18271 tuner
Configure the tda18271 to use a smaller transaction size by default, which
works around some sort of i2c bug in the Polaris driver (which needs to be
debugged).
This should be safe for other boards (being in tuner-core means it will be
enabled by default), although testing needs to be done.
[media] cx231xx: fix race condition in DVB initialization
Fix case where analog calls come in while the DVB side of the board is still
initializing. This patch is actually just an exact port of the same patch
made by Mauro to em28xx in hg rev 14762.
