* 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
|
||
|
|
|
||
|
|
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:
