Implement the V4L2_CID_MPEG_VIDEO_FORCE_KEY_FRAME control to force IDR
frames. This is useful to implement VFU (Video Fast Update) on RTP
transmissions.
We already force an IDR frame at the beginning of each GOP to work
around a firmware bug on i.MX27, use the same mechanism to service IDR
requests from userspace.

The driver may sleep under a spin lock, and the function call path is:
snd_cx18_pcm_hw_free (acquire the lock by spin_lock_irqsave)
vfree --> may sleep
To fix it, the "substream->runtime->dma_area" is passed to a temporary
value, and mark it NULL when holding the lock. The memory is freed by
vfree through the temporary value outside the lock holding.

The current driver has a handful of hard-coded assumptions based on its
primary use for capture of video signals. Cleanup those assumptions,
and also query the subdev for format information and use that if
available.
Tested with 10-bit raw bayer input (SGRBG10) using the aptina,mt9v032
sensor, and also tested that composite video input still works from
ti,tvp514x decoder. Both tests done on the da850-evm board with the
add-on UI board.
NOTE: Will need further testing for other sensors with different bus
formats.

Capture driver silently overrides pixel format with a hack (according to
the comments) to pass v4l2 compliance tests. This isn't needed for
normal functionality, and works for composite video and raw camera capture
without.
In addition, the hack assumes that it only supports raw capture with a
single format (SBGGR8) which isn't true. VPIF can also capture 10- and
12-bit raw formats as well. Forthcoming patches will enable VPIF
input with raw-camera support and has been tested with 10-bit format
from the aptina,mt9v032 sensor.
Any compliance failures should be fixed with a real fix.

The ir-spi driver has 2 issues which prevents it from working with
lirc:
1. The ir-spi driver uses 16 bits of SPI data to create one cycle of
the waveform. As such our SPI clock needs to be 16x faster than the
carrier frequency.
The driver is inconsistent in how it currently handles this. It
initializes it to the carrier frequency:
But the commit message has some example code which initialises it
to 16x the carrier frequency:
val = 608000;
ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val);
To maintain compatibility with lirc, always do the frequency adjustment
in the driver.
2. lirc presents pulses in microseconds, but the ir-spi driver treats
them as cycles of the carrier. Similar to other lirc drivers, do the
conversion with DIV_ROUND_CLOSEST().

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.

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.

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.

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.

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.

The lirc_zilog driver is the last remaining lirc driver, so the existing
todo is no longer relevant.

These functions are too short and removing them makes the code more

Several error paths do not free up resources. This simplifies the code
and fixes this.
