+MAXIM MAX14577 multi-function device
+
+MAX14577 is a Multi-function device with Micro-USB Interface Circuit, Li+
+Battery Charger and SFOUT LDO output for powering USB devices. It is
+interfaced to host controller using I2C.
+
+Required properties:
+- compatible : Must be "maxim,max14577".
+- reg : I2C slave address for the max14577 chip.
+- interrupts : IRQ line for the max14577 chip.
+- interrupt-parent : The parent interrupt controller.
+
+Optional nodes:
+- regulators :
+ Required child node properties:
+ - compatible : "maxim,max14577-regulator"
+
+ Optional child nodes:
+ Each child node representing a regulator, following standard regulator
+ bindings. Valid names for a regulator are: "CHARGER" and "SAFEOUT".
+ The SAFEOUT is a constant voltage regulator so there is no need to specify
+ voltages for it.
+
+ [*] refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+Example:
+ max14577@25 {
+ compatible = "maxim,max14577";
+ reg = <0x25>;
+ interrupt-parent = <&gpx1>;
+ interrupts = <5 0>;
+
+ regulators {
+ compatible = "maxim,max14577-regulator";
+
+ safeout_reg: safeout@1 {
+ regulator-compatible = "SAFEOUT";
+ regulator-name = "SAFEOUT";
+ };
+ charger_reg: charger@0 {
+ regulator-compatible = "CHARGER";
+ regulator-name = "CHARGER";
+ regulator-min-microamp = <90000>;
+ regulator-max-microamp = <950000>;
+ regulator-boot-on;
+ };
+ };
+ };
