Linus Torvalds 355ba37d75 Power management updates for 5.8-rc1
- Rework the system-wide PM driver flags to make them easier to
    understand and use and update their documentation (Rafael Wysocki,
    Alan Stern).
 
  - Allow cpuidle governors to be switched at run time regardless of
    the kernel configuration and update the related documentation
    accordingly (Hanjun Guo).
 
  - Improve the resume device handling in the user space hibernarion
    interface code (Domenico Andreoli).
 
  - Document the intel-speed-select sysfs interface (Srinivas
    Pandruvada).
 
  - Make the ACPI code handing suspend to idle print more debug
    messages to help diagnose issues with it (Rafael Wysocki).
 
  - Fix a helper routine in the cpufreq core and correct a typo in
    the struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
    Wenhu).
 
  - Update cpufreq drivers:
 
    * Make the intel_pstate driver start in the passive mode by
      default on systems without HWP (Rafael Wysocki).
 
    * Add i.MX7ULP support to the imx-cpufreq-dt driver and add
      i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
 
    * Convert the qoriq cpufreq driver to a platform one, make the
      platform code create a suitable device object for it and add
      platform dependencies to it (Mian Yousaf Kaukab, Geert
      Uytterhoeven).
 
    * Fix wrong compatible binding in the qcom driver (Ansuel Smith).
 
    * Build the omap driver by default for ARCH_OMAP2PLUS (Anders
      Roxell).
 
    * Add r8a7742 SoC support to the dt cpufreq driver (Lad Prabhakar).
 
  - Update cpuidle core and drivers:
 
    * Fix three reference count leaks in error code paths in the
      cpuidle core (Qiushi Wu).
 
    * Convert Qualcomm SPM to a generic cpuidle driver (Stephan
      Gerhold).
 
    * Fix up the execution order when entering a domain idle state in
      the PSCI driver (Ulf Hansson).
 
  - Fix a reference counting issue related to clock management and
    clean up two oddities in the PM-runtime framework (Rafael Wysocki,
    Andy Shevchenko).
 
  - Add ElkhartLake support to the Intel RAPL power capping driver
    and remove an unused local MSR definition from it (Jacob Pan,
    Sumeet Pawnikar).
 
  - Update devfreq core and drivers:
 
    * Replace strncpy() with strscpy() in the devfreq core and use
      lockdep asserts instead of manual checks for a locked mutex in
      it (Dmitry Osipenko, Krzysztof Kozlowski).
 
    * Add a generic imx bus scaling driver and make it register an
      interconnect device (Leonard Crestez, Gustavo A. R. Silva).
 
    * Make the cpufreq notifier in the tegra30 driver take boosting
      into account and delete an unuseful error message from that
      driver (Dmitry Osipenko, Markus Elfring).
 
  - Remove unneeded semicolon from the cpupower code (Zou Wei).

Pull power management updates from Rafael Wysocki:
 "These rework the system-wide PM driver flags, make runtime switching
  of cpuidle governors easier, improve the user space hibernation
  interface code, add intel-speed-select interface documentation, add
  more debug messages to the ACPI code handling suspend to idle, update
  the cpufreq core and drivers, fix a minor issue in the cpuidle core
  and update two cpuidle drivers, improve the PM-runtime framework,
  update the Intel RAPL power capping driver, update devfreq core and
