+* Ricoh RN5T618 PMIC
+
+Ricoh RN5T618 is a power management IC which integrates 3 step-down
+DCDC converters, 7 low-dropout regulators, a Li-ion battery charger,
+fuel gauge, ADC, GPIOs and a watchdog timer. It can be controlled
+through a I2C interface.
+
+Required properties:
+ - compatible: should be "ricoh,rn5t618"
+ - 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, LDO1,
+ LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.
+ 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>;
+ };
+ };
+ };
