Pull power management updates from Rafael Wysocki:
 "These include a significant update of the generic power domains
  (genpd) and Operating Performance Points (OPP) frameworks, mostly
  related to the introduction of power domain performance levels,
  cpufreq updates (new driver for Qualcomm Kryo processors, updates of
  the existing drivers, some core fixes, schedutil governor
  improvements), PCI power management fixes, ACPI workaround for
  EC-based wakeup events handling on resume from suspend-to-idle, and
  major updates of the turbostat and pm-graph utilities.

  Specifics:

   - Introduce power domain performance levels into the the generic
     power domains (genpd) and Operating Performance Points (OPP)
     frameworks (Viresh Kumar, Rajendra Nayak, Dan Carpenter).

   - Fix two issues in the runtime PM framework related to the
     initialization and removal of devices using device links (Ulf
     Hansson).

   - Clean up the initialization of drivers for devices in PM domains
     (Ulf Hansson, Geert Uytterhoeven).

   - Fix a cpufreq core issue related to the policy sysfs interface
     causing CPU online to fail for CPUs sharing one cpufreq policy in
     some situations (Tao Wang).

   - Make it possible to use platform-specific suspend/resume hooks in
     the cpufreq-dt driver and make the Armada 37xx DVFS use that
     feature (Viresh Kumar, Miquel Raynal).

   - Optimize policy transition notifications in cpufreq (Viresh Kumar).

   - Improve the iowait boost mechanism in the schedutil cpufreq
     governor (Patrick Bellasi).

   - Improve the handling of deferred frequency updates in the schedutil
     cpufreq governor (Joel Fernandes, Dietmar Eggemann, Rafael Wysocki,
     Viresh Kumar).

   - Add a new cpufreq driver for Qualcomm Kryo (Ilia Lin).

   - Fix and clean up some cpufreq drivers (Colin Ian King, Dmitry
     Osipenko, Doug Smythies, Luc Van Oostenryck, Simon Horman, Viresh
     Kumar).

   - Fix the handling of PCI devices with the DPM_SMART_SUSPEND flag set
     and update stale comments in the PCI core PM code (Rafael Wysocki).

   - Work around an issue related to the handling of EC-based wakeup
     events in the ACPI PM core during resume from suspend-to-idle if
     the EC has been put into the low-power mode (Rafael Wysocki).

   - Improve the handling of wakeup source objects in the PM core (Doug
     Berger, Mahendran Ganesh, Rafael Wysocki).

   - Update the driver core to prevent deferred probe from breaking
     suspend/resume ordering (Feng Kan).

   - Clean up the PM core somewhat (Bjorn Helgaas, Ulf Hansson, Rafael
     Wysocki).

   - Make the core suspend/resume code and cpufreq support the RT patch
     (Sebastian Andrzej Siewior, Thomas Gleixner).

   - Consolidate the PM QoS handling in cpuidle governors (Rafael
     Wysocki).

   - Fix a possible crash in the hibernation core (Tetsuo Handa).

   - Update the rockchip-io Adaptive Voltage Scaling (AVS) driver (David
     Wu).

   - Update the turbostat utility (fixes, cleanups, new CPU IDs, new
     command line options, built-in "Low Power Idle" counters support,
     new POLL and POLL% columns) and add an entry for it to MAINTAINERS
     (Len Brown, Artem Bityutskiy, Chen Yu, Laura Abbott, Matt Turner,
     Prarit Bhargava, Srinivas Pandruvada).

   - Update the pm-graph to version 5.1 (Todd Brandt).

   - Update the intel_pstate_tracer utility (Doug Smythies)"
