+TPS6586x family of regulators
+
+Required properties:
+- compatible: "ti,tps6586x"
+- reg: I2C slave address
+- interrupts: the interrupt outputs of the controller
+- #gpio-cells: number of cells to describe a GPIO
+- gpio-controller: mark the device as a GPIO controller
+- regulators: list of regulators provided by this controller, must be named
+ after their hardware counterparts: sm[0-2], ldo[0-9] and ldo_rtc
+
+Each regulator is defined using the standard binding for regulators.
+
+Example:
+
+ pmu: tps6586x@34 {
+ compatible = "ti,tps6586x";
+ reg = <0x34>;
+ interrupts = <0 88 0x4>;
