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.

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.

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.

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).

There are two places pointing to an unexisting "m.chehab@kernel.org"
email. I never had such email, so, I'm unsure how it ends there.
Anyway, it is plain wrong.
While here, use my canonical e-mail on a bunch of places that
are pointing to another e-mail. The idea is that, from now on,
all places will be pointing to the same SMTP server.

From now on, I'll start using my @kernel.org as my development e-mail.
As such, let's remove the entries that point to the old
mchehab@s-opensource.com at MAINTAINERS file.
For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.
For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.
For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

The v4l2_mbus_fmt width and height corresponds directly with the
v4l2_pix_format definitions, yet the differences in documentation make
it ambiguous what to do in the event of field heights.
Clarify this using the same text as is provided for the v4l2_pix_format
which is explicit on the matter, and by matching the terminology of
'image height' rather than the misleading 'frame height'.
