    Chen, Alexey Dobriyan).

    use case (He Zhe).

Pull power management updates from Rafael Wysocki:
 "The most significant change here is the extension of the Energy Model
  to cover non-CPU devices (as well as CPUs) from Lukasz Luba.

  There is also some new hardware support (Ice Lake server idle states
  table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
  RAPL driver), some new functionality in the existing drivers (eg. a
  new switch to disable/enable CPU energy-efficiency optimizations in
  intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
  core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
  devfreq), including the elimination of W=1 build warnings from cpufreq
  done by Lee Jones.

  Specifics:

   - Make the Energy Model cover non-CPU devices (Lukasz Luba).

   - Add Ice Lake server idle states table to the intel_idle driver and
     eliminate a redundant static variable from it (Chen Yu, Rafael
     Wysocki).
