Sorry I don't get it. Obviously the RPM backend here doesn't initialize
the TLL and if it only manages the clocks, can't we safely assume that
the pm_runtime_get_sync will get clocks to speed and the driver does
the TLL init ?

Ok, though if the ultimate goal is to move on to RPM, this would be a
step back.
Btw, which tree could I find the revert in ?

Thanks,
