+TPS62360 Voltage regulators
+
+Required properties:
+- compatible: Must be one of the following.
+	"ti,tps62360"
+	"ti,tps62361",
+	"ti,tps62362",
+	"ti,tps62363",
+- reg: I2C slave address
+
+Optional properties:
+- ti,enable-force-pwm: Enable force PWM mode. This is boolean value.
+- ti,enable-vout-discharge: Enable output discharge. This is boolean value.
+- ti,enable-pull-down: Enable pull down. This is boolean value.
+- ti,vsel0-gpio: GPIO for controlling VSEL0 line.
+  If this property is missing, then assume that there is no GPIO
+  for vsel0 control.
+- ti,vsel1-gpio: Gpio for controlling VSEL1 line.
+  If this property is missing, then assume that there is no GPIO
+  for vsel1 control.
+- ti,vsel0-state-high: Inital state of vsel0 input is high.
+  If this property is missing, then assume the state as low (0).
+- ti,vsel1-state-high: Inital state of vsel1 input is high.
+  If this property is missing, then assume the state as low (0).
+
+Any property defined as part of the core regulator binding, defined in
+regulator.txt, can also be used.
+
+Example:
+
+	abc: tps62360 {
+		compatible = "ti,tps62361";
+		reg =  <0x60>;
+		regulator-name = "tps62361-vout";
+		regulator-min-microvolt = <500000>;
+		regulator-max-microvolt = <1500000>;
+		regulator-boot-on
+		ti,vsel0-gpio = <&gpio1 16 0>;
+		ti,vsel1-gpio = <&gpio1 17 0>;
+		ti,vsel0-state-high;
+		ti,vsel1-state-high;
+		ti,enable-pull-down;
+		ti,enable-force-pwm;
+		ti,enable-vout-discharge;
+	};
