Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media 

Pull media updates from Mauro Carvalho Chehab:
 - some V4L2 API updates needed by embedded devices
 - DVB API extensions for ATSC-MH delivery system, used in US for mobile
   TV
 - new tuners for fc0011/0012/0013 and tua9001
 - a new dvb driver for af9033/9035
 - a new ATSC-MH frontend (lg2160)
 - new remote controller keymaps
 - Removal of a few legacy webcam driver that got replaced by gspca on
   several kernel versions ago
 - a new driver for Exynos 4/5 webcams(s5pp fimc-lite)
 - a new webcam sensor driver (smiapp)
 - a new video input driver for embedded (sta2x1xx)
 - several improvements, fixes, cleanups, etc inside the drivers.

Manually fix up conflicts due to err() -> dev_err() conversion in
drivers/staging/media/easycap/easycap_main.c

video signals and there is a need to extend the API to select the video timings
for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
the limited bits available, a new set of IOCTLs is added to set/get video timings at

<title>Description</title>
<para>The following four pixel formats are raw sRGB / Bayer formats
with 10 bits per colour compressed to 8 bits each, using DPCM
compression. DPCM, differential pulse-code modulation, is lossy.
Each colour component consumes 8 bits of memory. In other respects
this format is similar to <xref

<entry>V4L2_DV_FL_REDUCED_BLANKING</entry>
<entry>CVT/GTF specific: the timings use reduced blanking (CVT) or the 'Secondary
GTF' curve (GTF). In both cases the horizontal and/or vertical blanking
intervals are reduced, allowing a higher resolution over the same
bandwidth. This is a read-only flag, applications must not set this.
</entry>
</row>
<row>
<entry>V4L2_DV_FL_CAN_REDUCE_FPS</entry>
<entry>CEA-861 specific: set for CEA-861 formats with a framerate that is a multiple
of six. These formats can be optionally played at 1 / 1.001 speed to
be compatible with 60 Hz based standards such as NTSC and PAL-M that use a framerate of
29.97 frames per second. If the transmitter can't generate such frequencies, then the
flag will also be cleared. This is a read-only flag, applications must not set this.
</entry>
</row>
<row>
<entry>V4L2_DV_FL_REDUCED_FPS</entry>
<entry>CEA-861 specific: only valid for video transmitters, the flag is cleared
by receivers. It is also only valid for formats with the V4L2_DV_FL_CAN_REDUCE_FPS flag
set, for other formats the flag will be cleared by the driver.
If the application sets this flag, then the pixelclock used to set up the transmitter is
divided by 1.001 to make it compatible with NTSC framerates. If the transmitter
can't generate such frequencies, then the flag will also be cleared.
</entry>
</row>
<row>
<entry>V4L2_DV_FL_HALF_LINE</entry>
<entry>Specific to interlaced formats: if set, then field 1 (aka the odd field)
is really one half-line longer and field 2 (aka the even field) is really one half-line
shorter, so each field has exactly the same number of half-lines. Whether half-lines can be
detected or used depends on the hardware.

automatically, similar to sensing the video standard. To do so, applications
call <constant>VIDIOC_QUERY_DV_TIMINGS</constant> with a pointer to a

but the format is unsupported (e.g. because the pixelclock is out of range
of the hardware capabilities), then the driver fills in whatever timings it
could find and returns <errorcode>ERANGE</errorcode>. In that case the application
can call &VIDIOC-DV-TIMINGS-CAP; to compare the found timings with the hardware's
capabilities in order to give more precise feedback to the user.
