Subject: [PATCH 00/10] OPP: Support multiple power-domains per device

Hi,

This series improves the OPP core (and a bit of genpd core as well) to
support multiple phandles in the "required-opps" property, which are
only used for multiple power-domains per device for now.

We still don't propagate the changes to master domains for the
sub-domains, but this patchset is an important stepping stone for that
to happen.

Tested on Hikey960 after faking some power domains for CPUs.
