There are few GPU clocks which are powering up the memories
and thus enable the FORCE_MEM_PERIPH always for these clocks
to force the periph_on signal to remain active during halt
state of the clock.
I take it that missing this causes GPU to lose state when it suspends
and that confuses the driver?
It is more related to GPU SMMU states and the stability issues that are
encountered.
I see a very similar code sequence for sc7180. Is any similar fix
needed for sc7180, or is this something unique for sc7280?
This is not needed for sc7180, it is related to sc7280 only.
