Merge tag 'opp-updates-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm

Pull operating performance points (OPP) updates for 5.20-rc1 from Viresh
Kumar:

"- Make dev_pm_opp_set_regulators() accept NULL terminated list (Viresh
   Kumar).

 - Add dev_pm_opp_set_config() and friends and migrate other
   users/helpers to using them (Viresh Kumar).

 - Add support for multiple clocks for a device (Viresh Kumar and
   Krzysztof Kozlowski).

 - Configure resources before adding OPP table for Venus (Stanimir
   Varbanov).

 - Keep reference count up for opp->np and opp_table->np while they are
   still in use (Liang He).

 - Minor cleanups (Viresh Kumar and Yang Li)."
