    sysfs file permissions depend on the governor and clean up the
    devfreq core (Chanwoo Choi).
 
  - Clean up the tegra20 devfreq driver and deprecate it to allow
    another driver based on EMC_STAT to be used instead of it (Dmitry
    Osipenko).
 
  - Add interconnect support to the tegra30 devfreq driver, allow it
    to take the interconnect and OPP information from DT and clean it

    with interconnect properties documentation (Sylwester Nawrocki).

    capping driver (Victor Ding, Kim Phillips).
 
  - Fix handling of overly long constraint names in the powercap
    framework (Lukasz Luba).
 
  - Fix the wakeup configuration handling for bridges in the ACPI
    device power management core (Rafael Wysocki).
 
  - Add support for using an abstract scale for power units in the
    Energy Model (EM) and document it (Lukasz Luba).
 
  - Add em_cpu_energy() micro-optimization to the EM (Pavankumar
    Kondeti).
 
  - Modify the generic power domains (genpd) framwework to support
    suspend-to-idle (Ulf Hansson).

    driver flags for devices with debug enabled (Alex Shi, Patrice
    Chotard, Chen Yu).

    power off to avoid confusing the platform firmware (Kai-Heng Feng).

    and cpupower (online and offline CPU information support) PM
    utilities (Todd Brandt, Brahadambal Srinivasan).
