regulator: tps62360: add dt support
Add dt support for the pmu device tps62360 and Add binding documentation with example. With this patch driver will support both device-tree and non-device tree registration. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

+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;
+ };
