  Nordic nPM1300 PMIC

  The PMIC has two buck converters and two LDOs.
  The regulators need to be defined as child nodes, strictly following the
  BUCK1,2 LDO1..2, node names. For
  example:

  pmic@6b {
    reg = <0x6b>;
    ...
    regulators {
      compatible = "nordic,npm1300-regulator";

      BUCK1 {
        /* all properties for BUCK1 */
      };
      BUCK2 {
        /* all properties for BUCK2 */
      };
      LDO1 {
        /* all properties for LDO1 */
      };
      LDO2 {
        /* all properties for LDO2 */
      };
    };
  };

compatible: "nordic,npm1300-regulator"

      Set_dvs_mode will drive these pins as follows:
        DVS mode 1 will enable the first pin
        DVS mode 2 will enable the second pin
        DVS mode 3 will drive the first and second pins
        etc.
      The effect of the mode change is defined by the enable-gpios
      and pwm_gpios fields for each of the regulator blocks.
