* Ricoh RN5T567/RN5T618 PMIC
Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
fuel gauge, and an ADC.
The RC5T619 additionnally includes USB charger detection and an RTC.
Required properties:
- compatible: must be one of
"ricoh,rn5t567"
"ricoh,rn5t618"
"ricoh,rc5t619"
- reg: the I2C slave address of the device
Optional properties:
- interrupts: interrupt mapping for IRQ
See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- system-power-controller:
See Documentation/devicetree/bindings/power/power-controller.txt
Sub-nodes:
- regulators: the node is required if the regulator functionality is
needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
(RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
LDO9, LDO10, LDORTC1 and LDORTC2.
LDO7-10 are specific to RC5T619.
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>;
interrupt-parent = <&gpio5>;
interrupts = <11 IRQ_TYPE_EDGE_FALLING>;
system-power-controller;
regulators {
DCDC1 {
regulator-min-microvolt = <1050000>;
regulator-max-microvolt = <1050000>;
};
DCDC2 {
regulator-min-microvolt = <1175000>;
regulator-max-microvolt = <1175000>;
};
};
};
