Merge tag 'pm-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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
  drivers, and clean up the cpupower utility.

  Specifics:

   - 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)"
