Maxim MAX77693 multi-function device
MAX77693 is a Multifunction device with the following submodules:
- PMIC,
- CHARGER,
- LED,
- MUIC,
- HAPTIC
It is interfaced to host controller using i2c.
This document describes the bindings for the mfd device.
Required properties:
- compatible : Must be "maxim,max77693".
- reg : Specifies the i2c slave address of PMIC block.
- interrupts : This i2c device has an IRQ line connected to the main SoC.
- interrupt-parent : The parent interrupt controller.
Optional properties:
- regulators : The regulators of max77693 have to be instantiated under subnod
named "regulators" using the following format.
regulators {
regualtor-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
standard regulator constratints[*].
};
[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
Example:
max77693@66 {
compatible = "maxim,max77693";
reg = <0x66>;
interrupt-parent = <&gpx1>;
interrupts = <5 2>;
regulators {
esafeout@1 {
regulator-compatible = "ESAFEOUT1";
regulator-name = "ESAFEOUT1";
regulator-boot-on;
};
esafeout@2 {
regulator-compatible = "ESAFEOUT2";
regulator-name = "ESAFEOUT2";
};
charger@0 {
regulator-compatible = "CHARGER";
regulator-name = "CHARGER";
regulator-min-microamp = <60000>;
regulator-max-microamp = <2580000>;
regulator-boot-on;
};
};
};
