+TPS65090 regulators

+Required properties:
+- compatible: "ti,tps65090"
+- reg: I2C slave address
+- interrupts: the interrupt outputs of the controller
+- regulators: A node that houses a sub-node for each regulator within the
+  device. Each sub-node is identified using the node's name, with valid
+  values listed below. The content of each sub-node is defined by the
+  standard binding for regulators; see regulator.txt.
+  dcdc[1-3], fet[1-7] and ldo[1-2] respectively.
+- vsys[1-3]-supply: The input supply for DCDC[1-3] respectively.
+- infet[1-7]-supply: The input supply for FET[1-7] respectively.
+- vsys-l[1-2]-supply: The input supply for LDO[1-2] respectively.
+
+Optional properties:
+- ti,enable-ext-control: This is applicable for DCDC1, DCDC2 and DCDC3.
+  If DCDCs are externally controlled then this property should be there.
+- "dcdc-ext-control-gpios: This is applicable for DCDC1, DCDC2 and DCDC3.
+  If DCDCs are externally controlled and if it is from GPIO then GPIO
+  number should be provided. If it is externally controlled and no GPIO
