Pull power management updates from Rafael Wysocki:
 "These add new hardware support (new Qualcomm SoC versions in cpufreq,
  RK3568/RK3588 in devfreq), extend the OPP (operating performance
  points) framework, improve cpufreq governors, fix issues and clean up
  code (most of the changes are in cpufreq and devfreq).

  Specifics:

   - Add support for several Qualcomm SoC versions and other similar
     changes (Christian Marangi, Dmitry Baryshkov, Luca Weiss, Neil
     Armstrong, Richard Acayan, Robert Marko, Rohit Agarwal, Stephan
     Gerhold and Varadarajan Narayanan)

   - Clean up the tegra cpufreq driver (Sumit Gupta)

   - Use of_property_read_reg() to parse "reg" in pmac32 driver (Rob
     Herring)

   - Add support for TI's am62p5 Soc (Bryan Brattlof)

   - Make ARM_BRCMSTB_AVS_CPUFREQ depends on !ARM_SCMI_CPUFREQ (Florian
     Fainelli)

   - Update Kconfig to mention i.MX7 as well (Alexander Stein)

   - Revise global turbo disable check in intel_pstate (Srinivas
     Pandruvada)

   - Carry out initialization of sg_cpu in the schedutil cpufreq
     governor in one loop (Liao Chang)

   - Simplify the condition for storing 'down_threshold' in the
     conservative cpufreq governor (Liao Chang)

   - Use fine-grained mutex in the userspace cpufreq governor (Liao
     Chang)

   - Move is_managed indicator in the userspace cpufreq governor into a
     per-policy structure (Liao Chang)

   - Rebuild sched-domains when removing cpufreq driver (Pierre Gondois)

   - Fix buffer overflow detection in trans_stats() (Christian Marangi)

   - Switch to dev_pm_opp_find_freq_(ceil/floor)_indexed() APIs to
     support specific devices like UFS which handle multiple clocks
     through OPP (Operating Performance Point) framework (Manivannan
     Sadhasivam)

   - Add perf support to the Rockchip DFI (DDR Monitor Module) devfreq-
     event driver:
      * Generalize rockchip-dfi.c to support new RK3568/RK3588 using
        different DDR type (Sascha Hauer).
      * Convert DT binding document format to yaml (Sascha Hauer).
      * Add perf support for DFI (a unit suitable for measuring DDR
        utilization) to rockchip-dfi.c to extend DFI usage (Sascha
        Hauer)

   - Add locking to the OPP handling code in the Mediatek CCI devfreq
     driver, because the voltage of shared OPP might be changed by
     multiple drivers (Mark Tseng, Dan Carpenter)

   - Use device_get_match_data() in the Samsung Exynos PPMU
     devfreq-event driver (Rob Herring)

   - Extend support for the opp-level beyond required-opps (Ulf Hansson)

   - Add dev_pm_opp_find_level_floor() (Krishna chaitanya chundru)

   - dt-bindings: Allow opp-peak-kBpsfor kryo CPUs, support Qualcomm
     Krait SoCs and document named opp-microvolt property (Bjorn
     Andersson, Dmitry Baryshkov and Christian Marangi)

   - Fix -Wunsequenced warning _of_add_opp_table_v1() (Nathan
     Chancellor)

   - General cleanup of OPP code (Viresh Kumar)

   - Use __get_safe_page() rather than touching the list in hibernation
     snapshot code (Brian Geffon)

   - Fix symbol export for _SIMPLE_ variants of _PM_OPS() (Raag Jadav)

   - Clean up sync_read handling in snapshot_write_next() (Brian Geffon)

   - Fix kerneldoc comments for swsusp_check() and swsusp_close() to
     better match code (Christoph Hellwig)

   - Downgrade BIOS locked limits pr_warn() in the Intel RAPL power
     capping driver to pr_debug() (Ville Syrjälä)

   - Change the minimum python version for the intel_pstate_tracer
     utility from 2.7 to 3.6 (Doug Smythies)"
