Merge branch 'opp/linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm

Merge an operating performance points (OPP) framework update for
5.7-rc2 from Viresh Kumar:

"This contains a single patch that lets the OPP core to be used by
 several IO drivers without making a lot of changes in them for the
 case where the same driver may be used by a platform with an OPP
 table or a clock node on another one. I am looking to get this into
 5.7 release itself, which will enable other users (in multiple
 frameworks) to get merged without waiting for the dependency to get
 resolved."
