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>; + }; + }; + }; |
