Subject: [PATCH 0/4] PM / Domains: Allow performance state propagation

Hi,

This series adds performance state propagation support in genpd core.
The propagation happens from the sub-domains to their masters. More
details can be found in the individual commit logs.

This is tested on hikey960 by faking power domains in such a way that
the CPU devices have two power domains and both of them have the same
master domain. The CPU device, as well as its power domains have
"required-opps" property set and the performance requirement from the
CPU eventually configures all the domains (2 sub-domains and 1 master).

@Rajendra: Will it be possible for you to run some tests and tell me if
some stuff is still missing as per Qcom requirements ?

Based on opp/linux-next branch (which is 4.20-rc1 +
multiple-power-domain-support-in-opp-core).
