  regulator: Add API to re-apply voltage to hardware
  regulator: Staticise non-exported functions in mc13892
  regulator: Only notify voltage changes when they succeed
  regulator: Provide a selector based set_voltage_sel() operation
  regulator: Factor out voltage set operation into a separate function
  regulator: Convert WM8994 to use get_voltage_sel()
  regulator: Convert WM835x to use get_voltage_sel()
  regulator: Allow modular build of mc13xxx-core
  regulator: support PMIC mc13892
  make mc13783 regulator code generic
  Change the register name definitions for mc13783
  mach-ux500: Updated and connected ab8500 regulator board configuration
  regulators: Removed macros for initialization of ab8500 regulators
  regulators: Added verbose debug messages to ab8500 regulators
