Todor Tomov 6e15bec49f media: v4l: Add new 10-bit packed grayscale format
The new format will be called V4L2_PIX_FMT_Y10P.
It is similar to the V4L2_PIX_FMT_SBGGR10P family formats
but V4L2_PIX_FMT_Y10P is a grayscale format.

Hans Verkuil d272bc92c4 media: rename MEDIA_ENT_F_DTV_DECODER to MEDIA_ENT_F_DV_DECODER
The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.

Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.

We keep an alias to avoid breaking userspace applications.

Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.

Niklas Söderlund 56ab8cdbc1 media: v4l: Add support for STD ioctls on subdev nodes
There is no way to control the standard of subdevices which are part of
a media device. The ioctls which exists all target video devices
explicitly and the idea is that the video device should talk to the
subdevice. For subdevices part of a media graph this is not possible and
the standard must be controlled on the subdev device directly.

Add four new ioctls to be able to directly interact with subdevices and
control the video standard; VIDIOC_SUBDEV_ENUMSTD, VIDIOC_SUBDEV_G_STD,
VIDIOC_SUBDEV_S_STD and VIDIOC_SUBDEV_QUERYSTD.

Keiichi Watanabe 2a75364d09 media: v4l2-ctrl: Add control for VP9 profile
Add a new control V4L2_CID_MPEG_VIDEO_VP9_PROFILE for VP9 profiles. This control
allows selecting the desired profile for VP9 encoder and querying for supported
profiles by VP9 encoder/decoder.

Though this control is similar to V4L2_CID_MPEG_VIDEO_VP8_PROFILE, we need to
separate this control from it because supported profiles usually differ between
VP8 and VP9.

Keiichi Watanabe 5520b9467a media: v4l2-ctrl: Change control for VP8 profile to menu control
Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make
V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to
select the desired profile for VP8 encoder and query for supported profiles by
VP8 encoder/decoder.

Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this control cannot be used for querying since
it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.

The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)

In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in
drivers of Qualcomm's venus and Samsung's s5p-mfc.

Having two somewhat similar and largely overlapping APIs is confusing,
especially since the older one appears in the docs before the newer
and most featureful counterpart.

Clarify all of this in several ways:
 - swap the two sections
 - give a name to the two APIs in the section names
 - add a note at the beginning of the CROP API section
 - update note about VIDIOC_CROPCAP

Also remove a note that is incorrect (correct wording is in
vidioc-cropcap.rst).

Luca Ceresoli e97c19074f media: doc: poll: fix links to dual-ioctl sections
Links like :ref:`VIDIOC_STREAMON` expand to "ioctl VIDIOC_STREAMON,
VIDIOC_STREAMOFF". Thus our reader will think we are talking about
STREAMON _and_ STREAMOFF, but only one of the two actually applies
in some cases.

Fix by adding a link title, so the reader will read only the correct
ioctl name.

Sean Young 5817b3d15e media: rc: no need to announce major number
Since commit a60d64b15c ("media: lirc: lirc interface should not be
a raw decoder"), the message in the documentation is incorrect as the
module name is rc_core, not lirc_dev. Since the message is not useful,
just make the message debug and remove it from the documentation.

Hans Verkuil ccac77dc71 media: document the reservedX fields in media_v2_topology
The MEDIA_IOC_G_TOPOLOGY documentation didn't document the reservedX
fields. Related to that was that the documented type of the num_* fields
was also wrong.

Fix both.
