1* Ricoh RN5T567/RN5T618 PMIC 2 3Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which 4integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators, 5GPIOs, and a watchdog timer. It can be controlled through an I2C interface. 6The RN5T618/RC5T619 provides additionally a Li-ion battery charger, 7fuel gauge, and an ADC. 8The RC5T619 additionnally includes USB charger detection and an RTC. 9 10Required properties: 11 - compatible: must be one of 12 "ricoh,rn5t567" 13 "ricoh,rn5t618" 14 "ricoh,rc5t619" 15 - reg: the I2C slave address of the device 16 17Sub-nodes: 18 - regulators: the node is required if the regulator functionality is 19 needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4 20 (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8, 21 LDO9, LDO10, LDORTC1 and LDORTC2. 22 LDO7-10 are specific to RC5T619. 23 The common bindings for each individual regulator can be found in: 24 Documentation/devicetree/bindings/regulator/regulator.txt 25 26Example: 27 28 pmic@32 { 29 compatible = "ricoh,rn5t618"; 30 reg = <0x32>; 31 32 regulators { 33 DCDC1 { 34 regulator-min-microvolt = <1050000>; 35 regulator-max-microvolt = <1050000>; 36 }; 37 38 DCDC2 { 39 regulator-min-microvolt = <1175000>; 40 regulator-max-microvolt = <1175000>; 41 }; 42 }; 43 }; 44
