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

10Required 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
17Optional properties:
18 - interrupts: interrupt mapping for IRQ
19   See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
20 - system-power-controller:
21   See Documentation/devicetree/bindings/power/power-controller.txt
22
23Sub-nodes:
24 - regulators: the node is required if the regulator functionality is
25   needed. The valid regulator names are: DCDC1, DCDC2, DCDC3, DCDC4
26   (RN5T567/RC5T619), LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, LDO8,
27   LDO9, LDO10, LDORTC1 and LDORTC2.
28   LDO7-10 are specific to RC5T619.
29   The common bindings for each individual regulator can be found in:
30   Documentation/devicetree/bindings/regulator/regulator.txt
