    Pull more power management and ACPI updates from Rafael Wysocki:
     "The only new feature in this batch is support for the ACPI _CCA device
      configuration object, which it a pre-requisite for future ACPI PCI
      support on ARM64, but should not affect the other architectures.
    
      The rest is fixes and cleanups, mostly in cpufreq (including
      intel_pstate), the Operating Performace Points (OPP) framework and
      tools (cpupower and turbostat).
    
      Specifics:
    
       - Support for the ACPI _CCA configuration object intended to tell the
         OS whether or not a bus master device supports hardware managed
         cache coherency and a new set of functions to allow drivers to
         check the cache coherency support for devices in a platform
         firmware interface agnostic way (Suravee Suthikulpanit, Jeremy
         Linton).
    
       - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X
         (Aaron Lu, Hans de Goede).
    
       - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers
         (Jon Medhurst, Nicolas Pitre).
    
       - kfree()-related fixup for the recently introduced CPPC cpufreq
         frontend (Markus Elfring).
    
       - intel_pstate fix reducing kernel log noise on systems where
         P-states are managed by hardware (Prarit Bhargava).
    
       - intel_pstate maintainers information update (Srinivas Pandruvada).
    
       - cpufreq core optimization related to the handling of delayed work
         items used by governors (Viresh Kumar).
    
       - Locking fixes and cleanups of the Operating Performance Points
         (OPP) framework (Viresh Kumar).
    
       - Generic power domains framework cleanups (Lina Iyer).
    
       - cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan, Thomas
         Renninger).
    
       - turbostat tool updates (Len Brown)"
