i tried to test the unicam driver on a Raspberry Pi 4 with the imx219
camera (based on 5.17-rc4). The unicam & imx219 driver probes and
/dev/video0 is created.
If a execute the first media-ctl command, it complains with invalid
argument 22. Is there a more fool-proof variant to configure this (a
script or something else)? I never used the unicam driver before.
Here is the output of
$ mediactl -d0 -p
