+TPS65217 family of regulators

+Required properties:
+- compatible: "ti,tps65217"
+- reg: I2C slave address
+- regulators: list of regulators provided by this controller, must be named
+ after their hardware counterparts: dcdc[1-3] and ldo[1-4]
+- regulators: This is the list of child nodes that specify the regulator
+ initialization data for defined regulators. Not all regulators for the given
+ device need to be present. The definition for each of these nodes is defined
+ using the standard binding for regulators found at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+
+ The valid names for regulators are:
+ tps65217: dcdc1, dcdc2, dcdc3, ldo1, ldo2, ldo3 and ldo4
