[media] ir-spi: Fix issues with lirc API
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

[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.

[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.
