description:
  The MT6363 SPMI PMIC provides 10 BUCK and 25 LDO (Low DropOut) regulators
  and can optionally provide overcurrent warnings with one ocp interrupt
  for each voltage regulator.

          Allowed Buck regulator operating modes allowed. Valid values below.
            0 - Normal mode with automatic power saving, reducing the switching
                frequency when light load conditions are detected
            1 - Forced Continuous Conduction mode (FCCM) for improved voltage
                regulation accuracy with constant switching frequency but lower
                regulator efficiency
            2 - Forced Low Power mode for improved regulator efficiency, used
                when no heavy load is expected, does not limit the maximum out
                current but unless only a light load is applied, there will be
                regulation accuracy and efficiency losses.
            3 - Forced Ultra Low Power mode for ultra low load, this greatly
                reduces the maximum output power, makes the regulator to be
                efficient only for ultra light load, and greatly reduces the
                quiescent current (Iq) of the buck.
