    Pull power management updates from Rafael Wysocki:
     "These are PM-runtime framework changes to use ktime instead of jiffies
      for accounting, new PM core flag to mark devices that don't need any
      form of power management, cpuidle updates including driver API
      documentation and a new governor, cpufreq updates including a new
      driver for Armada 8K, thermal cleanups and more, some energy-aware
      scheduling (EAS) enabling changes, new chips support in the intel_idle
      and RAPL drivers and assorted cleanups in some other places.
    
      Specifics:
    
       - Update the PM-runtime framework to use ktime instead of jiffies for
         accounting (Thara Gopinath, Vincent Guittot)
    
       - Optimize the autosuspend code in the PM-runtime framework somewhat
         (Ladislav Michl)
    
       - Add a PM core flag to mark devices that don't need any form of
         power management (Sudeep Holla)
    
       - Introduce driver API documentation for cpuidle and add a new
         cpuidle governor for tickless systems (Rafael Wysocki)
    
       - Add Jacobsville support to the intel_idle driver (Zhang Rui)
    
       - Clean up a cpuidle core header file and the cpuidle-dt and ACPI
         processor-idle drivers (Yangtao Li, Joseph Lo, Yazen Ghannam)
    
       - Add new cpufreq driver for Armada 8K (Gregory Clement)
    
       - Fix and clean up cpufreq core (Rafael Wysocki, Viresh Kumar, Amit
         Kucheria)
    
       - Add support for light-weight tear-down and bring-up of CPUs to the
         cpufreq core and use it in the cpufreq-dt driver (Viresh Kumar)
    
       - Fix cpu_cooling Kconfig dependencies, add support for CPU cooling
         auto-registration to the cpufreq core and use it in multiple
         cpufreq drivers (Amit Kucheria)
    
       - Fix some minor issues and do some cleanups in the davinci,
         e_powersaver, ap806, s5pv210, qcom and kryo cpufreq drivers
         (Bartosz Golaszewski, Gustavo Silva, Julia Lawall, Paweł Chmiel,
         Taniya Das, Viresh Kumar)
    
       - Add a Hisilicon CPPC quirk to the cppc_cpufreq driver (Xiongfeng
         Wang)
    
       - Clean up the intel_pstate and acpi-cpufreq drivers (Erwan Velu,
         Rafael Wysocki)
    
       - Clean up multiple cpufreq drivers (Yangtao Li)
    
       - Update cpufreq-related MAINTAINERS entries (Baruch Siach, Lukas
         Bulwahn)
    
       - Add support for exposing the Energy Model via debugfs and make
         multiple cpufreq drivers register an Energy Model to support
         energy-aware scheduling (Quentin Perret, Dietmar Eggemann, Matthias
         Kaehlcke)
    
       - Add Ice Lake mobile and Jacobsville support to the Intel RAPL
         power-capping driver (Gayatri Kammela, Zhang Rui)
    
       - Add a power estimation helper to the operating performance points
         (OPP) framework and clean up a core function in it (Quentin Perret,
         Viresh Kumar)
    
       - Make minor improvements in the generic power domains (genpd), OPP
         and system suspend frameworks and in the PM core (Aditya Pakki,
         Douglas Anderson, Greg Kroah-Hartman, Rafael Wysocki, Yangtao Li)"
