1 * Ricoh RN5T567/RN5T618 PMIC
2
3 Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
4 integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
5 GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
6 The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
7 fuel gauge, and an ADC.
8 The RC5T619 additionnally includes USB charger detection and an RTC.

10 Required 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
17 Optional properties:
18  - system-power-controller:
19    See Documentation/devicetree/bindings/power/power-controller.txt

21 Sub-nodes:
22  - regulators: the node is required if the regulator functionality is
23    needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
24    (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
25    LDO9, LDO10, LDORTC1 and LDORTC2.
26    LDO7-10 are specific to RC5T619.
27    The common bindings for each individual regulator can be found in:
