Mauro Carvalho Chehab b3d98135aa V4L/DVB (6981): Fix bugzillas 9686 and 9691
IR were not working for Winfast XP 2000 TV.

Gabor Nyekhelyi <n0gabor@vipmail.hu> wrote a hack some time ago:
http://marc.info/?l=linux-video&m=116362609323281&w=2

This patch fixes CodingStyle and commits the hack. I suspect that the proper
solution would be to find the proper mask_keydown for this IR. Anyway, better
to have this patch as a workaround.

Thanks to Stafan Talpalaru <stefantalpalaru@yahoo.com> for pointing the issue.

Mauro Carvalho Chehab 7f1711234e V4L/DVB (6384): Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIG
Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).

This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

Trent Piepho a8ab68bffe V4L/DVB (6392): bttv: Update initial image size when set via V4L1 VIDIOCMCAPTURE
The V4L1 spec says that the image size should be with with VIDIOCSWIN before
requesting buffers with VIDIOCGMBUF and capturing into them with
VIDIOCMCAPTURE.

But it seems that many apps don't do this.  They set the size using the fields
in the VIDIOCMCAPTURE ioctl.  The driver doesn't know what size to capture
until it actually starts to capture.  In particular, it doesn't know what size
to capture until it has already mmap the captured buffers.  Which is quite
stupid.  Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea.

Many drivers don't support this, including those using v4l1-compat.

The bttv does, which is probably the only reason such broken software is so
prevalent.

But, the driver doesn't adjust its idea of what size is being captured when it
is set this way.  If you try to query the driver's current setting with
v4l2-ctl, it won't be correct.

Trent Piepho 35378434e7 V4L/DVB (6391): bttv: SPICT ioctl doesn't work with vlc
The bttv driver instists that the depth specified in the call to VIDIOCSPICT
match the pixel format specified in the same call.

vlc doesn't set the depth field, which makes the SPICT ioctl always fail.

The V4L1 standard is not clear on how most operation are supposed to work, and
this is no exception.  The depth field would appear to be entirely redundant,
as the pixel format specifies a specific depth.  It could be that this field
was only meant for output from the *G*PICT ioctl and should be ignored in
*S*PICT.  This is in fact what the v4l1-compat wrapper does.

Add the Osprey 440 to the Bt878 ALSA driver's whitelist.  Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.

Setting the audio gain via ALSA isn't supported yet; a userspace tool that
programs the X9221 via i2c-dev must be used.

The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC
used, resulting in extremely garbled sound.  That is fixed in a followup
patch.

Trent Piepho ac7dc84584 V4L/DVB (5805): Bttv: Fix problems with probing for non-existent tuners
The bttv driver has code to detect if a tda9887 is present, that was previous
used to auto-load the tda9887 driver.  Now there is no tda9887 driver, so the
code is pointless; it just figures out if it should load the driver and then
does nothing.

For cards that are defined as having no tuner, the init code would still do
i2c probes for various tuner devices and auto-load the tuner module.  That can
be skipped for cards that don't need it.  The code is made to understand that
in addition to 'UNSET', 'TUNER_ABSENT' also means no tuner.

The tuner into printk()s are also made nicer.  Levels are added, INFO or
WARNING, depending on the meaning.  For cards with no tuner, or no tuner
defined, a more informative message is printed.

Card has no tuner, before patch:
bttv0: tuner type=-1
 or
bttv0: tuner type=4

After patch:

bttv0: tuner absent

Trent Piepho 333408f215 V4L/DVB (5808): Bttv: fix v4l1 breaking the driver
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as
the first user after the driver is loaded, the driver wedges itself and will
never capture properly.  Even if one uses a V4L2 application later, it still
won't work.

If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2
driver, then the driver will be ok.  One can then run a V4L1 application, and
it will work.

It turns out the problem is with norm changing and the crop support that was
added in 2.6.21.  The driver defaults to PAL, and keeps the last norm it was
set too across opens.  If one changes the norm via V4L1, the cropping
parameters are not reset like they should be, and they'll remain broken across
device opens.

This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl
VIDIOCSCHAN handler.  The norm is set via the existing call to set_input(),
which calls set_tvnorm(), which will reset the cropping values now that it is
able to detect the norm change.

Scott Alfter 1ebba670ed V4L/DVB (5497): Additional card support for bttv driver
SSAI (www.ssai.us) makes several Bt878-based capture cards that get used in our
surveillance, conferencing, and medical imaging systems.  The attached
relatively small patch adds support for these cards, which fall into two broad
* boards with one or more Bt878s, one or more composite inputs, and no S-video
  or tuner inputs
* boards with one Bt878, one composite input, one S-video input, and no tuner
  input
