All the clocks, interconenct and power domains look to me questionable.
AFAIK, most of it (if not all) is going to be removed.
Yeah.. I'm lukewarm on accepting any sa8775p changes until that qcs9100(?)

After considering the feedback provided on the subject, We have decided
to keep current SA8775p compatible and ABI compatibility in drivers.
Therefore, this patch is still needed, please continue to review this
patch.
Thank you for your input.
