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.

* 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>;
|

|
||||
interrupts = <11 IRQ_TYPE_EDGE_FALLING>;

DCDC1 {

regulator-min-microvolt = <1050000>;
|
||||
regulator-max-microvolt = <1050000>;
|
||||
};
|
||||
|
||||
DCDC2 {
|
||||
regulator-min-microvolt = <1175000>;
|
||||
regulator-max-microvolt = <1175000>;
|
||||
};
