Add a new V4L2_CID_BAND_STOP_FILTER integer control, which either switches the
band-stop filter off, or sets it to a certain strength.

With the changes this file suffered along the time, things got a little disorganized.
In particular, V4L2_PIX_FMT_YVYU were shown as a device-specific format, instead of
yet another variant of YUV.
There's no functional change on this patch. It just adds some comments and reorder
fourcc formats to their proper places.

This patch adds autobrightness (so that it can
be turned off to make the already present brightness
control work) and light frequency filtering controls.
The lightfreq control needed 2 different entries
in the ctrls array, as the number of options differs
depending on the sensor. Always one of the 2 entires is
disabled ofcourse.

Modifies gspca and the videodev2.h header to create the necessary

The code in the new sq905c.c is based upon the structure of the code in
gspca/sq905.c, and upon the code in libgphoto2/camlibs/digigr8, which supports
the same set of cameras in stillcam mode. I am a co-author of gspca/sq905.c and
I am the sole author of libgphoto2/camlibs/digigr8, which is licensed under the

This addition to the v4l2-api add definitions for the constants and
data structures used for sliced VBI data insertion into MPEG streams triggered
by V4L2_MPEG_STREAM_VBI_FMT_IVTV. This simply declares what the ivtv and
cx18 drivers and MythTV have already been doing and provides a proper data
structure definition to user space.

Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

This patch adds support for NV16 and NV61 pixel formats.
These pixel formats use two planes; one for 8-bit Y values and
one for interleaved 8-bit U and V values. NV16/NV61 formats are
very similar to NV12/NV21 with the exception that NV16/NV61 are
using the same number of lines for both planes. The difference
between NV16 and NV61 is the U and V byte order.
The fourcc values are extrapolated from the NV12/NV21 case.
