* STMicroelectronics STPMIC1 Power Management IC
Required properties:
- compatible: : "st,stpmic1"
- reg: : The I2C slave address for the STPMIC1 chip.
- interrupts: : The interrupt line the device is connected to.
- #interrupt-cells: : Should be 1.
- interrupt-controller: : Marks the device node as an interrupt controller.
Interrupt numbers are defined at
dt-bindings/mfd/st,stpmic1.h.
STPMIC1 consists in a varied group of sub-devices.
Each sub-device binding is be described in own documentation file.
Device Description
------ ------------
st,stpmic1-onkey : Power on key, see ../input/st,stpmic1-onkey.txt
st,stpmic1-regulators : Regulators, see ../regulator/st,stpmic1-regulator.txt
st,stpmic1-wdt : Watchdog, see ../watchdog/st,stpmic1-wdt.txt
Example:
#include <dt-bindings/mfd/st,stpmic1.h>
pmic: pmic@33 {
compatible = "st,stpmic1";
reg = <0x33>;
interrupt-parent = <&gpioa>;
interrupts = <0 2>;
interrupt-controller;
#interrupt-cells = <2>;
onkey {
compatible = "st,stpmic1-onkey";
interrupts = <IT_PONKEY_F 0>,<IT_PONKEY_R 1>;
interrupt-names = "onkey-falling", "onkey-rising";
power-off-time-sec = <10>;
};
watchdog {
compatible = "st,stpmic1-wdt";
};
regulators {
compatible = "st,stpmic1-regulators";
vdd_core: buck1 {
regulator-name = "vdd_core";
regulator-boot-on;
regulator-min-microvolt = <700000>;
regulator-max-microvolt = <1200000>;
};
vdd: buck3 {
regulator-name = "vdd";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-boot-on;
regulator-pull-down;
};
};
