+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>;
+
+		#gpio-cells = <2>;
+		gpio-controller;
+
+		regulators {
+			sm0_reg: sm0 {
