Okay, this change is too large and HW specific for a detailed review.
But I trust you and hope you will be around to fix regressions if I
apply it for 5.13? That kind of leads to the question if you want to
step up as the maintainer for this driver?

Only thing I noticed was a "BUG" and "BUG_ON" and wonder if we really
need to halt the kernel in that case. Maybe WARN is enough?

I'll apply the first five patches now, they look good to me.
