Hans Verkuil 21abebf06d media: vicodec: rename and use proper fwht prefix for codec
The codec source is generic and not vicodec specific. It can be used
by other drivers or userspace as well. So rename the source and header
to something more generic (codec-fwht.c/h) and prefix the defines, types
and functions with fwht_.

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.

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,

 - 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

The lirc daemon now fails to detect a raw IR device, both for transmit

can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

Athanasios Oikonomou f9d7912619 media: dvb_frontend: add physical layer scrambling support
This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX.

This 18 bit field, when present, carries the index of the DVB-S2 physical
layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
There is no explicit signalling method to convey scrambling sequence index
to the receiver. If S2 satellite delivery system descriptor is available
it can be used to read the scrambling sequence index (EN 300 468 table 41).

By default, gold scrambling sequence index 0 is used. The valid scrambling
sequence index range is from 0 to 262142.

Increase the DVB API version in order userspace to be aware of the changes.

Sean Young dde7edff35 media: lirc: when transmitting scancodes, block until transmit is done
The semantics for lirc IR transmit with raw IR is that the write call
should block until the IR is transmitted. Some drivers have no idea
when this actually is (e.g. mceusb), so there is a wait.

This is useful for userspace, as it might want to send a IR button press,
a gap of a predefined number of milliseconds, and then send a repeat
message.

It turns out that for transmitting scancodes this feature is even more
useful, as user space has no idea how long the IR is. So, maintain
the existing semantics for IR scancode transmit.

Mauro Carvalho Chehab b33494e950 media: dvb uAPI docs: get rid of examples section
That section is too outdated and got superseded by DVBv5 and
by libdvbv5.

Maybe some day we'll end adding updated examples there, but
while nobody has time or interest of doing that, just mention
that there and get rid of the current examples for good.
