    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).
    
       - Eliminate all W=1 build warnings from cpufreq (Lee Jones).
    
       - Add support for Sapphire Rapids and for Power Limit 4 to the Intel
         RAPL power capping driver (Sumeet Pawnikar, Zhang Rui).
    
       - Fix function name in kerneldoc comments in the idle_inject power
         capping driver (Yangtao Li).
    
       - Fix locking issues with cpufreq governors and drop a redundant
         "weak" function definition from cpufreq (Viresh Kumar).
    
       - Rearrange cpufreq to register non-modular governors at the
         core_initcall level and allow the default cpufreq governor to be
         specified in the kernel command line (Quentin Perret).
    
       - Extend, fix and clean up the intel_pstate driver (Srinivas
         Pandruvada, Rafael Wysocki):
    
           * Add a new sysfs attribute for disabling/enabling CPU
             energy-efficiency optimizations in the processor.
    
           * Make the driver avoid enabling HWP if EPP is not supported.
    
           * Allow the driver to handle numeric EPP values in the sysfs
             interface and fix the setting of EPP via sysfs in the active
             mode.
    
           * Eliminate a static checker warning and clean up a kerneldoc
             comment.
    
       - Clean up some variable declarations in the powernv cpufreq driver
         (Wei Yongjun).
    
       - Fix up the ->enter_s2idle callback definition to cover the case
         when it points to the same function as ->idle correctly (Neal Liu).
    
       - Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).
    
       - Make the PM core emit "changed" uevent when adding/removing the
         "wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).
    
       - Add a helper macro for declaring PM callbacks and use it in the MMC
         jz4740 driver (Paul Cercueil).
    
       - Fix white space in some places in the hibernate code and make the
         system-wide PM code use "const char *" where appropriate (Xiang
         Chen, Alexey Dobriyan).
    
       - Add one more "unsafe" helper macro to the freezer to cover the NFS
         use case (He Zhe).
    
       - Change the language in the generic PM domains framework to use
         parent/child terminology and clean up a typo and some comment
         fromatting in that code (Kees Cook, Geert Uytterhoeven).
    
       - Update the operating performance points OPP framework (Lukasz Luba,
         Andrew-sh.Cheng, Valdis Kletnieks):
    
           * Refactor dev_pm_opp_of_register_em() and update related drivers.
    
           * Add a missing function export.
    
           * Allow disabled OPPs in dev_pm_opp_get_freq().
    
       - Update devfreq core and drivers (Chanwoo Choi, Lukasz Luba, Enric
         Balletbo i Serra, Dmitry Osipenko, Kieran Bingham, Marc Zyngier):
    
           * Add support for delayed timers to the devfreq core and make the
             Samsung exynos5422-dmc driver use it.
    
           * Unify sysfs interface to use "df-" as a prefix in instance
             names consistently.
    
           * Fix devfreq_summary debugfs node indentation.
    
           * Add the rockchip,pmu phandle to the rk3399_dmc driver DT
             bindings.
    
           * List Dmitry Osipenko as the Tegra devfreq driver maintainer.
    
           * Fix typos in the core devfreq code.
    
       - Update the pm-graph utility to version 5.7 including a number of
         fixes related to suspend-to-idle (Todd Brandt).
    
       - Fix coccicheck errors and warnings in the cpupower utility (Shuah
         Khan).
    
       - Replace HTTP links with HTTPs ones in multiple places (Alexander A.
         Klimov)"
