+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@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@1 {
+ regulator-compatible = "SAFEOUT";
+ regulator-name = "SAFEOUT";
+ };
+ charger_reg: regulator@0 {
+ regulator-compatible = "CHARGER";
+ regulator-name = "CHARGER";
+ regulator-min-microamp = <90000>;
+ regulator-max-microamp = <950000>;
+ regulator-boot-on;
+ };
+ };
+};
