  NXP PCA9420 PMIC

  The PMIC has two buck converters and two LDOs. All need to be defined as
  children nodes, strictly following the BUCK1, BUCK2, LDO1 and LDO2 node names.
  For example:

  pmic@61 {
    reg = <0x61>;
    ...
    BUCK1 {
      /* all properties for BUCK1 */
    };
    BUCK2 {
      /* all properties for BUCK2 */
    };
    LDO1 {
      /* all properties for LDO1 */
    };
    LDO2 {
      /* all properties for LDO2 */
    };
  };

      VIN input current limit, in microamperes. Value reflects typical value,
      below you can find min/typical/max values:

      - 74 mA/85 mA/98 mA
      - 222 mA/255 mA/293 mA
      - 370 mA/425 mA/489 mA

      - 813 mA/935 mA/1075 mA
      - 961 mA/1105 mA/1271 mA

      To disable current limit, set property to zero. Defaults to 425mA, the IC
      default value.
