Linus Torvalds ef8006846a Power management updates for 5.1-rc1 
- 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).

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
