+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>;
+ };
