Merge branch 'pm-cpufreq'

* pm-cpufreq:
  intel_pstate: skip the driver if ACPI has power mgmt option
  cpufreq: ondemand: Remove redundant return statement
  cpufreq: move freq change notifications to cpufreq core
  cpufreq: distinguish drivers that do asynchronous notifications
  cpufreq/intel_pstate: Add static declarations to internal functions
  cpufreq: arm_big_little: reconfigure switcher behavior at run time
  cpufreq: arm_big_little: add in-kernel switching (IKS) support
  ARM: vexpress/TC2: register vexpress-spc cpufreq device
  cpufreq: arm_big_little: add vexpress SPC interface driver
  ARM: vexpress/TC2: add cpu clock support
  ARM: vexpress/TC2: add support for CPU DVFS
