* 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>; |
|
}; |
|
}; |
