1* Ricoh RN5T567/RN5T618 PMIC
2
3Ricoh RN5T567/RN5T618 is a power management IC family which integrates
43 to 4 step-down DCDC converters, 7 low-dropout regulators, GPIOs and
5a watchdog timer. The RN5T618 provides additionally a Li-ion battery
6charger, fuel gauge and an ADC. It can be controlled through an I2C
7interface.

9Required properties:
10 - compatible: must be one of
11 "ricoh,rn5t567"
12 "ricoh,rn5t618"
13 - reg: the I2C slave address of the device
14
15Sub-nodes:
16 - regulators: the node is required if the regulator functionality is
17 needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
18 (RN5T567), LDO1, LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.
19 The common bindings for each individual regulator can be found in:
20 Documentation/devicetree/bindings/regulator/regulator.txt

22Example:
23
24 pmic@32 {
25 compatible = "ricoh,rn5t618";
26 reg = <0x32>;
27
28 regulators {
29 DCDC1 {
30 regulator-min-microvolt = <1050000>;
31 regulator-max-microvolt = <1050000>;
32 };
33
34 DCDC2 {
35 regulator-min-microvolt = <1175000>;
36 regulator-max-microvolt = <1175000>;
37 };
38 };
39 };
