  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.

* 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



Optional properties:

 - interrupts: interrupt mapping for IRQ

   See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt

 - system-power-controller:

   See Documentation/devicetree/bindings/power/power-controller.txt



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>;

		interrupt-parent = <&gpio5>;

		interrupts = <11 IRQ_TYPE_EDGE_FALLING>;

		system-power-controller;



		regulators {

			DCDC1 {

				regulator-min-microvolt = <1050000>;

				regulator-max-microvolt = <1050000>;

			};



			DCDC2 {

				regulator-min-microvolt = <1175000>;

				regulator-max-microvolt = <1175000>;

			};

		};

	};
