The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is, the differences are: + DCDC4/DCDC5 + LDO7-10 + Slightly different output voltage/currents + 32kHz Output + RTC + USB Charger detection Signed-off-by: Pierre-Hugues Husson <phh@phh.me> Acked-by: Rob Herring <robh@kernel.org> 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
|
|
|
|
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>;
|
|
|
|
regulators {
|
|
DCDC1 {
|
|
regulator-min-microvolt = <1050000>;
|
|
regulator-max-microvolt = <1050000>;
|
|
};
|
|
|
|
DCDC2 {
|
|
regulator-min-microvolt = <1175000>;
|
|
regulator-max-microvolt = <1175000>;
|
|
};
|
|
};
