The MPEG2 state controls for the cedrus stateless MPEG2 driver are
not yet stable. Move them out of the public headers into media/mpeg2-ctrls.h.
Eventually, once this has stabilized, they will be moved back to the
public headers.
Unfortunately I had to cast the control type to a u32 in two switch
statements to prevent a compiler warning about a control type define
not being part of the enum.

We get a headers_check warning about the newly defined ioctl command
structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

Stateless video decoding engines require both the MPEG-2 slices and
associated metadata from the video stream in order to decode frames.
This introduces definitions for a new pixel format, describing buffers
with MPEG-2 slice data, as well as control structure sfor passing the
frame metadata to drivers.
This is based on work from both Florent Revest and Hugues Fruchet.

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.

When the imx-media driver was initially merged, there was a conflict
with 8d67ae25 ("media: v4l2-ctrls: Reserve controls for MAX217X") which
was not fixed up correctly, resulting in V4L2_CID_USER_MAX217X_BASE and
V4L2_CID_USER_IMX_BASE taking on the same value. Fix by assigning imx
CID base the next available range at 0x10b0.

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.

signal path, in order to filter noise from desired radio channel.
Add channel bandwidth control to tell the driver which is radio
channel width we want receive. Filters could be then adjusted by
the driver or hardware, using RF frequency and channel bandwidth
as a base of filter calculations.
On automatic mode (normal mode), bandwidth is calculated from sampling
rate or tuning info got from userspace. That new control gives
possibility to set manual mode and let user have more control for
filters.

Modern silicon RF tuners used nowadays has many controllable gain
stages on signal path. Usually, but not always, there is at least
3 gain stages. Also on some cases there could be multiple gain
stages within the ones specified here. However, I think that having
these three controllable gain stages offers enough fine-tuning for
real use cases.
1) LNA gain. That is first gain just after antenna input.
2) Mixer gain. It is located quite middle of the signal path, where
RF signal is down-converted to IF/BB.
3) IF gain. That is last gain in order to adjust output signal level
to optimal level for receiving party (usually demodulator ADC).
Each gain stage could be set rather often both manual or automatic
(AGC) mode. Due to that add separate controls for controlling
operation mode.

VPE is a block which consists of a single memory to memory path which
can perform chrominance up/down sampling, de-interlacing, scaling, and
color space conversion of raster or tiled YUV420 coplanar, YUV422
coplanar or YUV422 interleaved video formats.
We create a mem2mem driver based primarily on the mem2mem-testdev
example. The de-interlacer, scaler and color space converter are all
bypassed for now to keep the driver simple. Chroma up/down sampler
blocks are implemented, so conversion beteen different YUV formats is
possible.
Each mem2mem context allocates a buffer for VPE MMR values which it will
use when it gets access to the VPE HW via the mem2mem queue, it also
allocates a VPDMA descriptor list to which configuration and data
descriptors are added.
Based on the information received via v4l2 ioctls for the source and
destination queues, the driver configures the values for the MMRs, and
stores them in the buffer. There are also some VPDMA parameters like
frame start and line mode which needs to be configured, these are
configured by direct register writes via the VPDMA helper functions.
The driver's device_run() mem2mem op will add each descriptor based on
how the source and destination queues are set up for the given ctx, once
the list is prepared, it's submitted to VPDMA, these descriptors when
parsed by VPDMA will upload MMR registers, start DMA of video buffers on
the various input and output clients/ports.
When the list is parsed completely(and the DMAs on all the output ports
done), an interrupt is generated which we use to notify that the source
and destination buffers are done. The rest of the driver is quite
similar to other mem2mem drivers, we use the multiplane v4l2 ioctls as
the HW support coplanar formats.
