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:
 "This series contains:
   - Exynos s5p-mfc driver got support for VP8 encoder
   - Some SoC drivers gained support for asynchronous registration
     (needed for DT)
   - The RC subsystem gained support for RC activity LED;
   - New drivers added: a video decoder(adv7842), a video encoder
     (adv7511), a new GSPCA driver (stk1135) and support for Renesas
     R-Car (vsp1)
   - the first SDR kernel driver: mirics msi3101.  Due to some troubles
     with the driver, and because the API is still under discussion, it
     will be merged at staging for 3.12.  Need to rework on it
   - usual new boards additions, fixes, cleanups and driver
     improvements"

+
+	<para>This is a multi-planar, two-plane version of the YUV 4:2:0 format.
+The three components are separated into two sub-images or planes.
+<constant>V4L2_PIX_FMT_NV16M</constant> differs from <constant>V4L2_PIX_FMT_NV16
+</constant> in that the two planes are non-contiguous in memory, i.e. the chroma
+plane does not necessarily immediately follows the luma plane.
+The luminance data occupies the first plane. The Y plane has one byte per pixel.
+In the second plane there is chrominance data with alternating chroma samples.
+The CbCr plane is the same width and height, in bytes, as the Y plane.
+Each CbCr pair belongs to four pixels. For example,
+Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
+Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
+Y'<subscript>10</subscript>, Y'<subscript>11</subscript>.
+<constant>V4L2_PIX_FMT_NV61M</constant> is the same as <constant>V4L2_PIX_FMT_NV16M</constant>
