* Ricoh RN5T567/RN5T618 PMIC
Ricoh RN5T567/RN5T618 is a power management IC family which integrates
3 to 4 step-down DCDC converters, 7 low-dropout regulators, GPIOs and
a watchdog timer. The RN5T618 provides additionally a Li-ion battery
charger, fuel gauge and an ADC. It can be controlled through an I2C
interface.
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
Sub-nodes:
- regulators: the node is required if the regulator functionality is
needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
(RN5T567), LDO1, LDO2, LDO3, LDO4, LDO5, LDORTC1 and LDORTC2.
(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:

TPS65218 family of regulators
Required properties:
For tps65218 regulators/LDOs
- compatible:
- "ti,tps65218-dcdc1" for DCDC1
- "ti,tps65218-dcdc2" for DCDC2
- "ti,tps65218-dcdc3" for DCDC3

- reg: I2C slave address
Optional properties:
- Any optional property defined in bindings/regulator/regulator.txt
- List of regulators provided by this controller, must be named
after their hardware counterparts: dcdc[1-6] and ldo1
- This is the list of child nodes that specify the regulator
initialization data for defined regulators. Not all regulators for the given
device need to be present. The definition for each of these nodes is defined
using the standard binding for regulators found at ./regulator.txt.
The valid names for regulators are:
tps65217: regulator-dcdc1, regulator-dcdc2, regulator-dcdc3, regulator-dcdc4,
regulator-dcdc5, regulator-dcdc6, regulator-ldo1, regulator-ls3.
Each regulator is defined using the standard binding for regulators.

reg = <0x24>;
compatible = "ti,tps65218";
interrupts = <GIC_SPI 7 IRQ_TYPE_NONE>; /* NMIn */
