Maxim Semiconductor MAX8903 Battery Charger bindings



Required properties:

- compatible: "maxim,max8903" for MAX8903 Battery Charger

- dok-gpios: Valid DC power has been detected (active low, input), optional if uok-gpios is provided

- uok-gpios: Valid USB power has been detected (active low, input), optional if dok-gpios is provided



Optional properties:

- cen-gpios: Charge enable pin (active low, output)

- chg-gpios: Charger status pin (active low, input)

- flt-gpios: Fault pin (active low, output)

- dcm-gpios: Current limit mode setting (DC=1 or USB=0, output)

- usus-gpios: USB suspend pin (active high, output)





Example:



	max8903-charger {

		compatible = "maxim,max8903";

		dok-gpios = <&gpio2 3 GPIO_ACTIVE_LOW>;

		flt-gpios = <&gpio2 2 GPIO_ACTIVE_LOW>;

		chg-gpios = <&gpio3 15 GPIO_ACTIVE_LOW>;

		cen-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;

	};
