61c3b19f7b media: staging: media: Revert "media: zoran: remove deprecated driver"
This reverts commit 8dce4b265a.
The revert is slighly modified:
- Documentation/media/v4l-drivers/index.rst is ,ot restored since removed from tree
- drivers/staging/media/Makefile is not restored since the zoran driver
  is not compilable yet.

6ca3549d87 media: platform: s5p-mfc: Fix adding a standard frame skip mode control
Add proper control type to the recently introduced
V4L2_CID_MPEG_VIDEO_FRAME_SKIP_MODE control. This will forward it to
v4l2_ctrl_new_std_menu() not v4l2_ctrl_new_std(), what causes the
failure. This fixes the following warning during driver initialization:

s5p_mfc_enc_ctrls_setup:2671: Adding control (18) failed
s5p_mfc_open:811: Failed to setup mfc controls

bfea1d81b5 media: vidtv: fix decoding with gstreamer and Vlc
Neither Vlc nor Gstreamer likes the PES_scrambling_control bits.

In the case of GST, this can be seen with:

	$ GST_DEBUG=2 LANG=C gst-play-1.0 pcm_audio.ts

a61d7d19a3 media: vidtv: rewrite the adaption field logic
When compared with a stream generated via ffmpeg, it can be
noticed that the PES doesn't contain any PCR info. That could
cause problems with userspace decoding. So, rewrite the
logic that fills the adaptation info, in order to allow it

2f21772961 media: vidtv: cleanup SDT string identifiers
In order to better test userspace applications, add an encoding
for the strings. The original channel string is also too big.
As we're just playing the first compasses of the 5th Beethoven
Symphony, change the service name to just "Beethoven". Also,
add a provider's name. For such purpose, let's point it to
the Linux media community website.

With such changes, the SDT table now looks more like one got

fc4405a5f1 media: vidtv: cleanup PSI version numbers
There's no reason to use static vars to store PSI version
numbers.

Also, currently, version numbers are starting with 0x01,
because there's a code being called that increases it to
1 for all table initializer code, as the code may support
dynamic changes at the PS tables on some future.

So, let's just initialize them to 0x1f, in order for the
versions to be reported as starting from 0.

cae045f495 media: hist-v4l2.rst: remove :c:type from structs and enums
Using struct|enum :c:`type` here sounds a bad idea, as it may be
documenting data types that were already removed. Also, it makes
the file harder to read.

As automarkup.py should be able to handle those cases, let's
just get rid of the markup.

While not required by automarkup, in order to make easier for
grep, both type and names are now at the same line.

c3cfc5f484 media: cec-core.rst: fix warnings with Sphinx 3.0+
The new C domain code on Sphinx 3 is a lot more pedantic.
It only accepts real functions declared as c:function.

So, declarations like this are not valid:

	.. c:function::
	        int (*adap_enable)(struct cec_adapter *adap, bool enable);

Also, no blank lines are allowed after ".. c:function:", and
continuation lines should be like:

	.. c:function:
		int (void foo, \
		     int bar);

Change the logic there, in order to avoid lots of warnings
when built with Sphinx 3.x.

There are several :c:type: definitions there, in order to
do cross-references with the driver's documentation.

Those are broken when docs are built with Sphinx 3.x, as
it would require :c:struct: instead.

For Sphinx < 3.x, the automarkup.py extension is able to do the
replacement already, and a future improvement on it should make
it also work with Sphinx 3.x.

So, get rid of the usage of the :c:type: macro there.

In case those signals arrive together then the code is not able to

98c437e3b9 media: staging: rkisp1: params: avoid using buffer if params is not streaming
Currently, the first buffer queued in the params node is returned
immediately to userspace and a copy of it is saved in the field
'cur_params'. The copy is later used for the first configuration
when the stream is initiated by one of selfpath/mainpath capture nodes.

There are 3 problems with this implementation:
- The first params buffer is applied and returned to userspace even if
userspace never calls to streamon on the params node.
- If the first params buffer is queued after the stream started on the
params node then it will return to userspace but will never be used.
- The frame_sequence of the first buffer is set to -1 if the main/selfpath
did not start streaming.

A correct implementation is to apply the first params buffer when stream
is started from mainpath/selfpath and only if params is also streaming.

The patch adds a new function 'rkisp1_params_apply_params_cfg' which takes
a buffer from the buffers queue, apply it and returns it to userspace.
The function is called from the irq handler and when main/selfpath stream
starts - in the function 'rkisp1_params_config_parameter'

Also remove the fields 'cur_params', 'is_first_params' which are no
more needed.

ff1c9223b7 media: rc: gpio-ir-recv: add QoS support for cpuidle system
GPIO IR receive is much rely on interrupt response, uneven interrupt
latency will lead to incorrect timing, so the decoder fails to decode
it. The issue is particularly acute on some systems which support
cpuidle, not all, dynamically disable and enable cpuidle can solve this
problem to a great extent.

However, there is a downside to this approach, the measurement of header
on the first frame may incorrect. Test on i.MX8M serials, when enable
cpuidle, interrupt latency could be about 500us.

With this patch:
1. has no side effect on non-cpuidle system, even runtime pm api won't
be invoked to avoid a bunch of pm busy work for devices that do not need
it, including spinlocks, ktime, etc.
2. latency is still much longer for the first gpio interrupt on cpuidle
system, so the first frame may not be decoded. Generally, RC would transmit
multiple frames at once press, we can sacrifice the first frame.
3. add "linux,autosuspend-period" property in device tree if you also
suffer this cpuidle issue.

Constify a number of static structs that were not modified. In order to
be able to do that, const input arguments to a couple of functions that

read-only memory, resulting in about 6k memory being read-only, and the
resulting module is 400 bytes smaller.

e8897acb89 media: netup_unidvb: drop initialization of PM pointers
The .suspend() and .resume() callbacks are not defined for this driver.
Thus, just the unlisting of PM pointers in the struct initializer will make
no change in its behavior. Still unlisting is necessary so as to get rid of
.suspend and .resume pointers as they are part of the legacy framework and
should not be used in the driver code explicitly.

8c608272ec media: cedrus: Propagate OUTPUT resolution to CAPTURE
As per spec, the CAPTURE resolution should be automatically set based on
the OUTPUT resolution. This patch properly propagate width/height to the
capture when the OUTPUT format is set and override the user provided
width/height with configured OUTPUT resolution when the CAPTURE fmt is
updated.

This also prevents userspace from selecting a CAPTURE resolution that is
too small, avoiding kernel oops.
