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 17Optional properties: 18 - interrupts: interrupt mapping for IRQ 19 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt 20 - system-power-controller: 21 See Documentation/devicetree/bindings/power/power-controller.txt 22 23Sub-nodes: 24 - regulators: the node is required if the regulator functionality is 25 needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4 26 (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8, 27 LDO9, LDO10, LDORTC1 and LDORTC2. 28 LDO7-10 are specific to RC5T619. 29 The common bindings for each individual regulator can be found in: 30 Documentation/devicetree/bindings/regulator/regulator.txt 31 32Example: 33 34 pmic@32 { 35 compatible = "ricoh,rn5t618"; 36 reg = <0x32>; 37 interrupt-parent = <&gpio5>; 38 interrupts = <11 IRQ_TYPE_EDGE_FALLING>; 39 system-power-controller; 40 41 regulators { 42 DCDC1 { 43 regulator-min-microvolt = <1050000>; 44 regulator-max-microvolt = <1050000>; 45 }; 46 47 DCDC2 { 48 regulator-min-microvolt = <1175000>; 49 regulator-max-microvolt = <1175000>; 50 }; 51 }; 52 }; 53
