Linus Torvalds b35b6d4d71 Power management updates for 5.17-rc1
- Add new P-state driver for AMD processors (Huang Rui).

    cpufreq core (Rafael Wysocki).
 
  - Fix EPP handling on Alder Lake in intel_pstate (Srinivas Pandruvada).
 
  - Make intel_pstate update cpuinfo.max_freq when notified of HWP
    capabilities changes and drop a redundant function call from that
    driver (Rafael Wysocki).
 
  - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
    Stephen Boyd, Vladimir Zapolskiy).
 
  - Fix double devm_remap() in the Mediatek cpufreq driver (Hector Yuan).
 
  - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
    Luba).

    code (Rafael Wysocki).
 
  - Capture device status before disabling runtime PM for it (Rafael
    Wysocki).

    avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
    update some drivers to use these macros (Paul Cercueil).

    hibernation (David Woodhouse).

Pull power management updates from Rafael Wysocki:
 "The most signigicant change here is the addition of a new cpufreq
  'P-state' driver for AMD processors as a better replacement for the
  venerable acpi-cpufreq driver.

  There are also other cpufreq updates (in the core, intel_pstate, ARM
  drivers), PM core updates (mostly related to adding new macros for
  declaring PM operations which should make the lives of driver
  developers somewhat easier), and a bunch of assorted fixes and
  cleanups.

  Summary:

   - Add new P-state driver for AMD processors (Huang Rui).

   - Fix initialization of min and max frequency QoS requests in the
     cpufreq core (Rafael Wysocki).

   - Fix EPP handling on Alder Lake in intel_pstate (Srinivas
     Pandruvada).

   - Make intel_pstate update cpuinfo.max_freq when notified of HWP

   - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).

   - Fix two comments in cpuidle code (Jason Wang, Yang Li).

   - Allow model-specific normal EPB value to be used in the intel_epb
     sysfs attribute handling code (Srinivas Pandruvada).
