859969b38e [media] v4l: Switch from V4L2 OF not V4L2 fwnode API
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.

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.

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.

Fault simulation/injection is by executing the following USB operation

After setting halt state for the TX endpoint, perform an lirc "irsend"
to generate TX traffic to device. After the TX HALT, the patch restores
subsequent TX to working state.

configuration but it may not be the case for all available products.

The irq number is used in the probe function only, therefore just use
a local variable.

5c80992e8f [media] mceusb: fix inaccurate debug buffer dumps, and misleading debug messages
Some dev_dbg messages are misleading. Some dev_dbg messages have
inconsistent formatting. mceusb_dev_printdata() prints incorrect range
of bytes (0 to len) in buffer which the driver will actually process next.

8e175b22e8 [media] mceusb: sporadic RX truncation corruption fix
Intermittent RX truncation and loss of IR received data. This resulted
in receive stream synchronization errors where driver attempted to
incorrectly parse IR data (eg 0x90 below) as command response.

834ebbc8f3 [media] coda: simplify optional reset handling
As of commit bb475230b8 ("reset: make optional functions really
optional"), the reset framework API calls use NULL pointers to
describe optional, non-present reset controls.

This allows to return errors from devm_reset_control_get_optional
without special cases and to call reset_control_reset unconditionally.

Add a timer to automatically stop/start the data pump if we
