Linus Torvalds 0b8417c141 Power management updates for 5.10-rc1
- Rework cpufreq statistics collection to allow it to take place
    when fast frequency switching is enabled in the governor (Viresh
    Kumar).
 
  - Make the cpufreq core set the frequency scale on behalf of the
    driver and update several cpufreq drivers accordingly (Ionela
    Voinescu, Valentin Schneider).
 
  - Add new hardware support to the STI and qcom cpufreq drivers and
    improve them (Alain Volmat, Manivannan Sadhasivam).
 
  - Fix multiple assorted issues in cpufreq drivers (Jon Hunter,
    Krzysztof Kozlowski, Matthias Kaehlcke, Pali Rohár, Stephan
    Gerhold, Viresh Kumar).
 
  - Fix several assorted issues in the operating performance points
    (OPP) framework (Stephan Gerhold, Viresh Kumar).
 
  - Allow devfreq drivers to fetch devfreq instances by DT enumeration
    instead of using explicit phandles and modify the devfreq core
    code to support driver-specific devfreq DT bindings (Leonard
    Crestez, Chanwoo Choi).
 
  - Improve initial hardware resetting in the tegra30 devfreq driver
    and clean up the tegra cpuidle driver (Dmitry Osipenko).
 
  - Update the cpuidle core to collect state entry rejection
    statistics and expose them via sysfs (Lina Iyer).
 
  - Improve the ACPI _CST code handling diagnostics (Chen Yu).
 
  - Update the PSCI cpuidle driver to allow the PM domain
    initialization to occur in the OSI mode as well as in the PC
    mode (Ulf Hansson).
 
  - Rework the generic power domains (genpd) core code to allow
    domain power off transition to be aborted in the absence of the
    "power off" domain callback (Ulf Hansson).
 
  - Fix two suspend-to-idle issues in the ACPI EC driver (Rafael
    Wysocki).
 
  - Fix the handling of timer_expires in the PM-runtime framework on
    32-bit systems and the handling of device links in it (Grygorii
    Strashko, Xiang Chen).
 
  - Add IO requests batching support to the hibernate image saving and
    reading code and drop a bogus get_gendisk() from there (Xiaoyi
    Chen, Christoph Hellwig).
 
  - Allow PCIe ports to be put into the D3cold power state if they
    are power-manageable via ACPI (Lukas Wunner).
 
  - Add missing header file include to a power capping driver (Pujin
    Shi).
 
  - Clean up the qcom-cpr AVS driver a bit (Liu Shixin).
 
  - Kevin Hilman steps down as designated reviwer of adaptive voltage
    scaling (AVS) driverrs (Kevin Hilman).

Pull power management updates from Rafael Wysocki:
 "These rework the collection of cpufreq statistics to allow it to take
  place if fast frequency switching is enabled in the governor, rework
