Merge tag 'pm-5.20-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These are ARM cpufreq updates and operating performance points (OPP)
  updates plus one cpuidle update adding a new trace point.

  Specifics:

   - Fix return error code in mtk_cpu_dvfs_info_init (Yang Yingliang).

   - Minor cleanups and support for new boards for Qcom cpufreq drivers
     (Bryan O'Donoghue, Konrad Dybcio, Pierre Gondois, and Yicong Yang).

   - Fix sparse warnings for Tegra cpufreq driver (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 and
     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 OPP cleanups (Viresh Kumar and Yang Li).

   - Add a trace event for cpuidle to track missed (too deep or too
     shallow) wakeups (Kajetan Puchalski)"
