+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:
+- max14577-muic :
+	Node used only by extcon consumers.
+	Required properties:
+		- compatible : "maxim,max14577-muic"
+
+- regulators :
+	Required properties:
+		- compatible : "maxim,max14577-regulator"
+
+	May contain a sub-node per regulator from the list below. Each
+	sub-node should contain the constraints and initialization information
+	for that regulator. See regulator.txt for a description of standard
+	properties for these sub-nodes.
+
+	List of valid regulator names: CHARGER, SAFEOUT.
+
+	The SAFEOUT is a fixed voltage regulator so there is no need to specify
+	voltages for it.
+
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>
+
+max14577 at 25 {
+	compatible = "maxim,max14577";
+	reg = <0x25>;
+	interrupt-parent = <&gpx1>;
+	interrupts = <5 IRQ_TYPE_NONE>;
+
+	muic: max14577-muic {
+		compatible = "maxim,max14577-muic";
+	};
+
+	regulators {
+		compatible = "maxim,max14577-regulator";
+
+		safeout_reg: regulator at 1 {
+			regulator-compatible = "SAFEOUT";
+			regulator-name = "SAFEOUT";
+		};
+		charger_reg: regulator at 0 {
+			regulator-compatible = "CHARGER";
+			regulator-name = "CHARGER";
+			regulator-min-microamp = <90000>;
+			regulator-max-microamp = <950000>;
+			regulator-boot-on;
+		};
+	};
+};
