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

Pull operating performance points (OPP) changes for v5.12 from Viresh
Kumar:

"- Generic cleanups across the OPP core (Dmitry Osipenko, Viresh
   Kumar).

 - New OPP helpers dev_pm_opp_find_level_ceil(),
   dev_pm_opp_get_required_pstate(), dev_pm_opp_sync_regulators(),
   devm_pm_opp_register_set_opp_helper(),
   dev_pm_opp_of_add_table_noclk() and devm_pm_opp_attach_genpd()
   (Dmitry Osipenko, Viresh Kumar).

 - Allow required OPPs to be used for devfreq devices and related
   changes to devfreq governor (Saravana Kannan).

 - Significant code changes to allow a new OPP helper,
   dev_pm_opp_set_opp() (Viresh Kumar).

 - Remove dev_pm_opp_set_bw() and update related drivers (Viresh
   Kumar).

 - Allow lazy linking of required-OPPs (Viresh Kumar)."
