RPMH based targets require that the sleep and wake state request votes

last cpu enters low power mode. So add cpu power domain using Linux
generic power domain infrastructure to perform necessary tasks as part
of domain power down.

You seem to have either randomly chosen just 3 patches from Lina/Ulf's
CPU genpd series or this series doesn't entirely depend on it ?

If latter, how does this work with PSCI CPU_SUSPEND operations ?

And why this can be part of PSCI firmware implementation. Only PSCI
firmware needs if RPMH votes need to be flushed or not. So, honestly
I don't see the need for this in Linux.
