drm/vc4: module dysfunctional on Raspberry Pi 3B as of 5.18.0

[Stefan Wahren]

Hi Peter,

i didn't subscribe to dri-devel, but i noticed your bug report.

Could you please provide more information:

Which kernel config do you use (is it a defconfig)?
Do you use the mainline device tree blob or the Raspberry Pi DTB?
Please provide the version/date of the GPU firmware?
Do you have any KMS related setting in the config.txt?
Can you provide a full dmesg for the bad case?

Best regards
