The video_ioctl2 conversion replaced the default from NTSC to PAL_BG.
This broke cx88-blackbird. Probably, there are some badness at this
driver, not doing all required stuff to change video standard.Signed-off-by: Mauro Carvalho Chehab

This patch finishes cx88-blackbird conversion to use video_ioctl2. Video
standards are generated automatically inside videodev.c. the big ioctl
parser is removed, using, instead, video_ioctl2.Signed-off-by: Mauro Carvalho Chehab

v4l2_tvnorm were meant to describe video standards and its names to V4L2 API.
However, this were doing by some static structures at the driver.This patch changes the internals in a way that, at the driver, only a
v4l2_tvnorm (a 64 bit integer) should be filled, with all supported
tvnorms. videodev will dynamically generate the proper API array
based on supported standards.Signed-off-by: Mauro Carvalho Chehab

video_ioctl2 handler provides V4L2 API parsing.
Using it makes the driver simpler, and isolates API parsing.
This allows future reusage of driver controls using other ways, like sysfs
and/or procfs and increases isolation of driver-specific handling from the
generic common ioctl processing.Signed-off-by: Mauro Carvalho Chehab

With the previous patch, mplayer started but was polling the video
device forever without any video actually coming out. Further analysis
showed that it does a VIDIOC_S_FMT with width and height set to -1 (!!!).
The code handling this only cares that both are lower than the minimum
range allowed so it ends up setting the size to 19x17 (!!) This pretty
much breaks the encoder here. Even if this breakage is yet another (TM)
result of my setup, setting the size to 19x17 by default would surprise
most users IMHO.
So, special case for -1 and interpret this to be a request for the
default size, please. Users can then set their favorite size both
through mplayer and through sysfs.
With this patch, mplayer finally works in pvr:// mode (not that we
really gain anything over operating it through sysfs with lirc,
sometime I might actually get off my lazy a** and contribute this
setup too)Signed-off-by: Pantelis Koukousoulas

This should allow mplayer pvr:// to start. The trick is that no matter
what actual input we use under this "fake" one, it will be able to do
stereo :-)Signed-off-by: Pantelis Koukousoulas

Audio mode changes are not private to the audio chip - other I2C
modules need to see this as well. And since the command in question
is VIDIOC_S_TUNER which is a standard v4l2 command, we really should
be broadcasting it out. This change sets up a broadcast pathway for
VIDIOC_S_TUNER and also eliminates the now redundant code from the
audio chip handler.
This fix enables stereo reception for the FM radioSigned-off-by: Mike Isely

Attempts to enumerate or operate on a group of EXT_CTRLS where the
group size is zero is OK; don't fail on such operations. At least one
application uses this to probe for the existence of this API so let it
succeed.Signed-off-by: Mike Isely

The automodeswitch control was a feature that enable automatic radio /
tv switching based on the selected frequency. However since frequency
ranges can overlap and also since apparently in some cases it's
possible for the same frequency range to be both tv and radio in a
specific region, then this feature can't safely work. So it's removed.Signed-off-by: Mike Isely

Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting
applications to capture or overlay a subsection of the picture or to
extend the capture window beyond active video, into the VBI area and the
horizontal blanking. VBI capturing can start and end on any line,
including the picture area, and apps can capture different lines of each
field and single fields.
For compatibility with existing applications, the open() function
resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP
call is necessary to actually enable cropping.
Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image
width will increase from 640 and 768 to 747 and 923 pixels respectively.
Like the VBI changes however, this should only affect applications which
depend on former driver limitations, such as never getting more than 640
pixels regardless of the requested width.
Also, new freedoms require additional checks for conflicts and some
applications may not expect an EBUSY error from the VIDIOC_QBUF and
VIDIOCMCAPTURE ioctls. These errors should be rare though.
So far, the patch has been tested on a UP machine with a bt878 in PAL-
BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/
libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2

Clean up and tighten logic involving stream configuration. This
mainly involves changes to pvrusb2-v4l2.c, where we better clarify how
we use the stream configuration enum and implement a cleaner means to
