    Pull power management updates from Rafael Wysocki:
     "These add ACPI support to the intel_idle driver along with an admin
      guide document for it, add support for CPR (Core Power Reduction) to
      the AVS (Adaptive Voltage Scaling) subsystem, add new hardware support
      in a few places, add some new sysfs attributes, debugfs files and
      tracepoints, fix bugs and clean up a bunch of things all over.
    
      Specifics:
    
       - Update the ACPI processor driver in order to export
         acpi_processor_evaluate_cst() to the code outside of it, add ACPI
         support to the intel_idle driver based on that and clean up that
         driver somewhat (Rafael Wysocki).
    
       - Add an admin guide document for the intel_idle driver (Rafael
         Wysocki).
    
       - Clean up cpuidle core and drivers, enable compilation testing for
         some of them (Benjamin Gaignard, Krzysztof Kozlowski, Rafael
         Wysocki, Yangtao Li).
    
       - Fix reference counting of OPP (operating performance points) table
         structures (Viresh Kumar).
    
       - Add support for CPR (Core Power Reduction) to the AVS (Adaptive
         Voltage Scaling) subsystem (Niklas Cassel, Colin Ian King,
         YueHaibing).
    
       - Add support for TigerLake Mobile and JasperLake to the Intel RAPL
         power capping driver (Zhang Rui).
    
       - Update cpufreq drivers:
          - Add i.MX8MP support to imx-cpufreq-dt (Anson Huang).
          - Fix usage of a macro in loongson2_cpufreq (Alexandre Oliva).
          - Fix cpufreq policy reference counting issues in s3c and
            brcmstb-avs (chenqiwu).
          - Fix ACPI table reference counting issue and HiSilicon quirk
            handling in the CPPC driver (Hanjun Guo).
          - Clean up spelling mistake in intel_pstate (Harry Pan).
          - Convert the kirkwood and tegra186 drivers to using
            devm_platform_ioremap_resource() (Yangtao Li).
    
       - Update devfreq core:
          - Add 'name' sysfs attribute for devfreq devices (Chanwoo Choi).
          - Clean up the handing of transition statistics and allow them to
            be reset by writing 0 to the 'trans_stat' devfreq device
            attribute in sysfs (Kamil Konieczny).
          - Add 'devfreq_summary' to debugfs (Chanwoo Choi).
          - Clean up kerneldoc comments and Kconfig indentation (Krzysztof
            Kozlowski, Randy Dunlap).
    
       - Update devfreq drivers:
          - Add dynamic scaling for the imx8m DDR controller and clean up
            imx8m-ddrc (Leonard Crestez, YueHaibing).
          - Fix DT node reference counting and nitialization error code path
            in rk3399_dmc and add COMPILE_TEST and HAVE_ARM_SMCCC dependency
            for it (Chanwoo Choi, Yangtao Li).
          - Fix DT node reference counting in rockchip-dfi and make it use
            devm_platform_ioremap_resource() (Yangtao Li).
          - Fix excessive stack usage in exynos-ppmu (Arnd Bergmann).
          - Fix initialization error code paths in exynos-bus (Yangtao Li).
          - Clean up exynos-bus and exynos somewhat (Artur Świgoń, Krzysztof
            Kozlowski).
    
       - Add tracepoints for tracking usage_count updates unrelated to
         status changes in PM-runtime (Michał Mirosław).
    
       - Add sysfs attribute to control the "sync on suspend" behavior
         during system-wide suspend (Jonas Meurer).
    
       - Switch system-wide suspend tests over to 64-bit time (Alexandre
         Belloni).
    
       - Make wakeup sources statistics in debugfs cover deleted ones which
         used to be the case some time ago (zhuguangqing).
    
       - Clean up computations carried out during hibernation, update
         messages related to hibernation and fix a spelling mistake in one
         of them (Wen Yang, Luigi Semenzato, Colin Ian King).
    
       - Add mailmap entry for maintainer e-mail address that has not been
         functional for several years (Rafael Wysocki)"
