  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
