Linus Torvalds 1e2af254ef Power management updates for 4.21-rc1
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
 
  - Make it possible to specify a cpuidle governor from kernel
    command line, add new cpuidle state sysfs attributes for
    governor evaluation, and improve the "polling" idle state
    handling (Rafael Wysocki).
 
  - Fix the handling of the "required-opps" DT property in the
    operating performance points (OPP) framework, improve the
    integration of it with the generic power domains (genpd)
    framework, improve the handling of performance states in
    them and clean up the idle states vs performance states
    separation in genpd (Viresh Kumar, Ulf Hansson).
 
  - Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
    a hardware engine to control CPU frequency transitions along
    with DT bindings for it (Taniya Das).
 
  - Fix an intel_pstate driver issue related to CPU offline and
    update the documentation of it (Srinivas Pandruvada).
 
  - Clean up the imx6q cpufreq driver (Anson Huang).
 
  - Add SPDX license IDs to cpufreq schedutil governor files (Daniel
    Lezcano).
 
  - Switch over the runtime PM framework to using high-res timers
    for device autosuspend to allow the control of it to be more
    precise (Vincent Guittot).
 
  - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
    don't prevent the system from reaching the target low-power state
    and simplify the suspend-to-idle handling on ACPI platforms
    without full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
 
  - Add system-wide suspend and resume support to the devfreq
    framework (Lukasz Luba).
 
  - Clean up the SmartReflex adaptive voltage scaling (AVS) driver and
    add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
    Thomas Meyer).
 
  - Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
    macro in some places, fix some DT node refcount leaks, and do
    some other janitorial cleanups (Yangtao Li).
 
  - Update the cpupower, intel_pstate_tracer and turbosat utilities
    (Abhishek Goel, Doug Smythies, Len Brown).

Pull power management updates from Rafael Wysocki:
 "These add sysadmin documentation for cpuidle, extend the cpuidle
  subsystem somewhat, improve the handling of performance states in the
  generic power domains (genpd) and operating performance points (OPP)
  frameworks, add a new cpufreq driver for Qualcomm SoCs, update some
  other cpufreq drivers, switch over the runtime PM framework to using
  high-res timers for device autosuspend, fix a problem with
  suspend-to-idle on ACPI-based platforms, add system-wide suspend and
  resume handling to the devfreq framework, do some janitorial cleanups
  all over and update some utilities.
