Since its a new hardware, please provide v4l2-compliance test results along with
relevant fluster result for the decoder part. Please also provide a link to your
submission of the related SCP firmware to the linux-firmware project. This way I
don't have to ask if/when the firmware will land.

cheers,
Nicolas
