Unfortunately it does not work when CONFIG_DRM_ETNAVIV=m
etnaviv-gpu 38000000.gpu: model: GC0, revision: 0
etnaviv-gpu 38000000.gpu: Unknown GPU model
etnaviv-gpu 38008000.gpu: model: GC0, revision: 0
etnaviv-gpu 38008000.gpu: Unknown GPU model

When I use CONFIG_DRM_ETNAVIV=y, I get the same log message as you. It's not 
related to this patch, but I have no clue if the cause is in blk-ctrl or pgc.

I think (don't know for sure yet) my random errors on USB side are gone when 
USB drivers (PHY as well) are built-in. But I might be wrong here.

Best regards,
Alexander
