Dave Stevenson 3cb0fe6f74 [media] tc358743: Add enum_mbus_code
There was no way to query the supported mbus formats from this
driver. enum_mbus_code is the function to expose that, so
implement it.

Hans Verkuil a7a04b5b2c [media] cec: improve debug messages
- use __func__ instead of writing the full function name
- drop debug message in cec_config_log_addr since the same information
  will be reported later
- use debug level 1 for errors and infrequent events, use level 2 for
  debugging CEC message traffic
- log when a transmit is retried, very useful to know when debugging
- debug messages now all start with lower case

Nori, Sekhar 8946ab3a4c [media] davinci: vpif_capture: fix default pixel format for BT.656/BT.1120 video
For both BT.656 and BT.1120 video, the pixel format
used by VPIF is Y/CbCr 4:2:2 in semi-planar format
(Luma in one plane and Chroma in another). This
corresponds to NV16 pixel format.

This is documented in section 36.2.3 of OMAP-L138
Technical Reference Manual, SPRUH77A.

The VPIF driver incorrectly sets the default format
to V4L2_PIX_FMT_YUV422P. Fix it.

Niklas Söderlund 82ec4ca9b5 [media] rcar-vin: allow switch between capturing modes when stalling
If userspace can't feed the driver with buffers as fast as the driver
consumes them the driver will stop video capturing and wait for more
buffers from userspace, the driver is stalled. Once it have been feed
one or more free buffers it will recover from the stall and resume
capturing.

Instead of continue to capture using the same capture mode as before the
stall allow the driver to choose between single and continuous mode
based on free buffer availability. Do this by stopping capturing when
the driver becomes stalled and restart capturing once it continues. By
doing
this the capture mode will be evaluated each time the driver is
recovering from a stall.

This behavior is needed to fix a bug where continuous capturing mode is
used, userspace is about to stop the stream and is waiting for the last
buffers to be returned from the driver and is not queuing any new
buffers. In this case the driver becomes stalled when there are only 3
buffers remaining streaming will never resume since the driver is
waiting for userspace to feed it more buffers before it can continue
streaming.  With this fix the driver will then switch to single capture
mode for the last 3 buffers and a deadlock is avoided. The issue can be
demonstrated using yavta.

$ yavta -f RGB565 -s 640x480 -n 4 --capture=10  /dev/video22

<blocks forever, waiting for the last buffer>

This fix also allow the driver to switch to single capture mode if
userspace doesn't feed it buffers fast enough. Or the other way around,
if userspace suddenly feeds the driver buffers faster it can switch to
continues capturing mode.

Niklas Söderlund 996ce3afbe [media] rcar-vin: select capture mode based on free buffers
Instead of selecting single or continuous capture mode based on how many
buffers userspace intends to give us select capture mode based on number
of free buffers we can allocate to hardware when the stream is started.

This change is a prerequisite to enable the driver to switch from
continuous to single capture mode (or the other way around) when the
driver is stalled by userspace not feeding it buffers as fast as it
consumes it.

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs.
Async OF matching is replaced by fwnode matching and OF matching support
is removed.

Sakari Ailus ecdf0cfe71 [media] v4l: async: Add fwnode match support
Add fwnode matching to complement OF node matching. And fwnode may also be
an OF node.

Do not enable fwnode matching yet. It will replace OF matching soon.

Sakari Ailus ca50c197bd [media] v4l: fwnode: Support generic fwnode for parsing standardised properties
The fwnode_handle is a more generic way than OF device_node to describe
firmware nodes. Instead of the OF API, use more generic fwnode API to
obtain the same information.

As the V4L2 fwnode support will be required by a small minority of e.g.
ACPI based systems (the same might actually go for OF), make this a module
instead of embedding it in the videodev module.

The origins of the V4L2 fwnode framework is in the V4L2 OF framework.

Fix all checkpatch reported issues for:

 * CHECK: "braces {} should be used on all arms of this statement".
 * CHECK: "Unbalanced braces around else statement".

Make sure all if/else statements are balanced in terms of braces. Most
cases in code are, but a few were left unbalanced, so put them all
consistent with the recommended style.

Fix style issues reported by checkpatch, affecting whitespace only:

 * CHECK: "Please don't use multiple blank lines".
   Two of these still triggering and left untouched because used for

 * CHECK: "spaces preferred around that '<operator>'".
   All fixed.

 * CHECK: "Alignment should match open parenthesis".
   All fixed except one on line 1161, left untouched for readability.
