I was sure your will be asking. :-)
I am using RPi4[0] for testing this. Device tree is based on sources from here [1]. From this devicetree it is obvious what is happening.
Unfortunately right now SUSE Bugzilla is under maintenance, so perhaps you can't see the bug report [2]. In brief I am using latest Tumbleweed on this device and you can imagine that error is happening always.
Regards, Ivan
