    Pull power management updates from Rafael Wysocki:
     "These fix the (Intel-specific) Performance and Energy Bias Hint (EPB)
      handling and expose it to user space via sysfs, fix and clean up
      several cpufreq drivers, add support for two new chips to the qoriq
      cpufreq driver, fix, simplify and clean up the cpufreq core and the
      schedutil governor, add support for "CPU" domains to the generic power
      domains (genpd) framework and provide low-level PSCI firmware support
      for that feature, fix the exynos cpuidle driver and fix a couple of
      issues in the devfreq subsystem and clean it up.
    
      Specifics:
    
       - Fix the handling of Performance and Energy Bias Hint (EPB) on Intel
         processors and expose it to user space via sysfs to avoid having to
         access it through the generic MSR I/F (Rafael Wysocki).
    
       - Improve the handling of global turbo changes made by the platform
         firmware in the intel_pstate driver (Rafael Wysocki).
    
       - Convert some slow-path static_cpu_has() callers to boot_cpu_has()
         in cpufreq (Borislav Petkov).
    
       - Fix the frequency calculation loop in the armada-37xx cpufreq
         driver (Gregory CLEMENT).
    
       - Fix possible object reference leaks in multuple cpufreq drivers
         (Wen Yang).
    
       - Fix kerneldoc comment in the centrino cpufreq driver (dongjian).
    
       - Clean up the ACPI and maple cpufreq drivers (Viresh Kumar, Mohan
         Kumar).
    
       - Add support for lx2160a and ls1028a to the qoriq cpufreq driver
         (Vabhav Sharma, Yuantian Tang).
    
       - Fix kobject memory leak in the cpufreq core (Viresh Kumar).
    
       - Simplify the IOwait boosting in the schedutil cpufreq governor and
         rework the TSC cpufreq notifier on x86 (Rafael Wysocki).
    
       - Clean up the cpufreq core and statistics code (Yue Hu, Kyle Lin).
    
       - Improve the cpufreq documentation, add SPDX license tags to some PM
         documentation files and unify copyright notices in them (Rafael
         Wysocki).
    
       - Add support for "CPU" domains to the generic power domains (genpd)
         framework and provide low-level PSCI firmware support for that
         feature (Ulf Hansson).
    
       - Rearrange the PSCI firmware support code and add support for
         SYSTEM_RESET2 to it (Ulf Hansson, Sudeep Holla).
    
       - Improve genpd support for devices in multiple power domains (Ulf
         Hansson).
    
       - Unify target residency for the AFTR and coupled AFTR states in the
         exynos cpuidle driver (Marek Szyprowski).
    
       - Introduce new helper routine in the operating performance points
         (OPP) framework (Andrew-sh.Cheng).
    
       - Add support for passing on-die termination (ODT) and auto power
         down parameters from the kernel to Trusted Firmware-A (TF-A) to the
         rk3399_dmc devfreq driver (Enric Balletbo i Serra).
    
       - Add tracing to devfreq (Lukasz Luba).
    
       - Make the exynos-bus devfreq driver suspend all devices on system
         shutdown (Marek Szyprowski).
    
       - Fix a few minor issues in the devfreq subsystem and clean it up
         somewhat (Enric Balletbo i Serra, MyungJoo Ham, Rob Herring,
         Saravana Kannan, Yangtao Li).
    
       - Improve system wakeup diagnostics (Stephen Boyd).
    
       - Rework filesystem sync messages emitted during system suspend and
         hibernation (Harry Pan)"
