[libcamera-devel] [PATCH 0/6] Raspberry Pi: Conversion to media controller

[Naushir Patuck]

Hi,

This series of patches convert the Raspberry Pi pipeline handler to a more
media controller centric mode of operation.  In particular, we set/get formats
and controls directly on the sensor subdevice instead of proxying through the
unicam driver node.

Note that these changes rely on https://github.com/raspberrypi/linux/pull/4645
being merged into our kernel tree.  That merge will need to be synchronised with
merging this change into the libcamera upstream tree else we will have a mismatch
between kernel and userland.  In such cases, the pipeline handler will throw an
error and fail to start.

Thanks,
Naush
