Pull media documentation updates from Mauro Carvalho Chehab: "This patch series does the conversion of all media documentation stuff to Restrutured Text markup format and add them to the Documentation/index.rst file. The media documentation was grouped into 4 books: - media uAPI - media kAPI - V4L driver-specific documentation - DVB driver-specific documentation It also contains several documentation improvements and one fixup patch for a core issue with cropcap. PS. After this patch series, the media DocBook is deprecated and should be removed. I'll add such patch on a future pull request" * tag 'media/v4.8-4' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (322 commits) [media] cx23885-cardlist.rst: add a new card [media] doc-rst: add some needed escape codes [media] doc-rst: kapi: use :c:func: instead of :cpp:func doc-rst: kernel-doc: fix a change introduced by mistake [media] v4l2-ioctl.h add debug info for struct v4l2_ioctl_ops [media] dvb_ringbuffer.h: some documentation improvements [media] v4l2-ctrls.h: fully document the header file [media] doc-rst: Fix some typedef ugly warnings [media] doc-rst: reorganize the kAPI v4l2 chapters [media] rename v4l2-framework.rst to v4l2-intro.rst [media] move V4L2 clocks to a separate .rst file [media] v4l2-fh.rst: add cross references and markups [media] v4l2-fh.rst: add fh contents from v4l2-framework.rst [media] v4l2-fh.h: add documentation for it [media] v4l2-event.rst: add cross-references and markups [media] v4l2-event.h: document all functions [media] v4l2-event.rst: add text from v4l2-framework.rst [media] v4l2-framework.rst: remove videobuf quick chapter [media] v4l2-dev: add cross-references and improve markup [media] doc-rst: move v4l2-dev doc to a separate file ...

+V4L2_PIX_FMT_YVU444M
+Planar formats with full horizontal resolution, also known as YUV and
+YVU 4:4:4
+
+
+Description
+===========
+
+This is a multi-planar format, as opposed to a packed format. The three
+components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. For
+``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
+is the same width and height as the Y plane (and as the image). The Cr
+data, just like the Cb plane, is in the third plane.
+
+``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
+second plane and the Cb data in the third plane.
+
+If the Y plane has pad bytes after each row, then the Cb and Cr planes
+have the same number of pad bytes after their rows.
+
+``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
+used only in drivers and applications that support the multi-planar API,
+described in :ref:`planar-apis`.
+
+**Byte Order.**
+Each cell is one byte.
