• Ricoh RN5T567/RN5T618 PMIC

Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
fuel gauge, and an ADC.
The RC5T619 additionnally includes USB charger detection and an RTC.

Required properties:

• compatible: must be one of

   "ricoh,rn5t567"
   "ricoh,rn5t618"
   "ricoh,rc5t619"
  

• reg: the I2C slave address of the device

Sub-nodes:

• regulators: the node is required if the regulator functionality is
  needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
  (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
  LDO9, LDO10, LDORTC1 and LDORTC2.
  LDO7-10 are specific to RC5T619.
  The common bindings for each individual regulator can be found in:
  Documentation/devicetree/bindings/regulator/regulator.txt

Example:

pmic@32 {
    compatible = "ricoh,rn5t618";
    reg = <0x32>;

    regulators {
        DCDC1 {
            regulator-min-microvolt = <1050000>;
            regulator-max-microvolt = <1050000>;
        };

        DCDC2 {
            regulator-min-microvolt = <1175000>;
            regulator-max-microvolt = <1175000>;
        };
    };
};
