The required-opps should no longer be necessary.
Sure, will check and remove this if not required.
I checked further on this and without required-opps, if there is no vote
on the power-domain & its peer from any other consumers, when runtime
get is called on device, it enables the power domain just at the minimum
non-zero level. But in some cases, the minimum non-zero level of
power-domain could be just retention and is not sufficient for clock
controller to operate, hence required-opps property is needed to specify
the minimum level required on power-domain for this clock controller.
Thanks,
