+* Powerventure Semiconductor PV88060 Voltage Regulator
+
+Required properties:
+- compatible: "pvs,pv88060".
+- reg: I2C slave address, usually 0x49.
+- 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.
+  BUCK1, LDO1, LDO2, LDO3, LDO4, LDO5, LDO6, LDO7, SW1, SW2, SW3, SW4,
+  SW5, and SW6.
+
+Optional properties:
+- Any optional property defined in regulator.txt
