The RN5T618 family of PMICs can be used as system management controllers, in which case they handle poweroff and restart. Document this capability by referring to the corresponding generic DT binding. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* 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:
|
|
- 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>;
|
|
system-power-controller;
|
|
|
|
regulators {
|
|
DCDC1 {
|
|
regulator-min-microvolt = <1050000>;
|
|
regulator-max-microvolt = <1050000>;
|
|
};
|
|
|
|
DCDC2 {
|
|
regulator-min-microvolt = <1175000>;
|
|
regulator-max-microvolt = <1175000>;
|
|
};
|
|
};
|
|
};
