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)"
