commit db0340182444612bcadb98bdec22f651aa42266c upstream.
The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.Signed-off-by: Hans Verkuil

commit 7ec2b3b941a666a942859684281b5f6460a0c234 upstream.
If the HDMI cable is disconnected or the CEC adapter is manually
unconfigured, then all pending transmits and wait-for-replies are
aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED).If due to (usually) a driver bug a transmit never ends (i.e. the
transmit_done was never called by the driver), then when this times
out the message is marked with CEC_TX_STATUS_TIMEOUT.This should not happen and is an indication of a driver bug.
Without a separate status bit for this it was impossible to detect
this from userspace.The 'transmit timed out' kernel message is now a warning, so this
should be more prominent in the kernel log as well.Signed-off-by: Hans Verkuil

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.Signed-off-by: Hans Verkuil

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.Signed-off-by: Niklas Söderlund

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.Signed-off-by: Keiichi Watanabe

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.Signed-off-by: Keiichi Watanabe

- give a name to the two APIs in the section names
- add a note at the beginning of the CROP API section
