[PATCH v2 00/12] media: uvcvideo: Add support for orientation and rotation.

[Ricardo Ribalda <ribalda@chromium.org>]

The ACPI has ways to annotate the location of a USB device. Wire that
annotation to a v4l2 control.

To support all possible devices, add a way to annotate USB devices on DT
as well. The original binding discussion happened here:
https://lore.kernel.org/linux-devicetree/20241212-usb-orientation-v1-1-0b69adf05f37@chromium.org/

The following patches are needed regardless if we finally add support
for orientation and rotation or not:
- media: uvcvideo: Always set default_value
- media: uvcvideo: Do not create MC entities for virtual entities
