+MAX77650 ultra low-power PMIC from Maxim Integrated.
+
+Required properties:
+-------------------
+- compatible:		Must be "maxim,max77650"
+- reg:			I2C device address.
+- interrupts:		The interrupt on the parent the controller is
+			connected to.
+- interrupt-parent:	phandle of the parent interrupt controller.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells:	Must be <2>.
+
+For device-tree bindings of sub-modules (regulator, power supply, GPIO, LEDs
+and onkey) refer to the binding documents under the respective sub-system
+directories.
+
+Example:
+--------
+
+	pmic: max77650@48 {
+		compatible = "maxim,max77650";
+		reg = <0x48>;
+
+		interrupt-controller;
+		interrupt-parent = <&gpio2>;
+		#interrupt-cells = <2>;
+		interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
+	};
