+Maxim Semiconductor MAX8903 Battery Charger bindings
+
+Required properties:
+- compatible: "maxim,max8903-charger" for MAX8903 Battery Charger
+- dc_valid: Specifies that the DC portion of the MAX8903 has been connected up
+ and that dok-gpios should be specified
+ - dok-gpios: Valid DC power has been detected
+- usb_valid: Specifies that the USB portion of the MAX8903 has been connected up
+ and that uok-gpios should be specified
+ - uok-gpios: Valid USB power has been detected
+
+Optional properties:
+- cen-gpios: Charge enable pin
+- chg-gpios: Charger status pin
+- flt-gpios: Fault pin
+- dcm-gpios: Current limit mode setting (DC or USB)
+- usus-gpios: USB suspend pin
+
+
+Example:
+
+ max8903-charger {
+ compatible = "maxim,max8903-charger";
+ 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>;
+ dc_valid;
+ status = "okay";
+ };
