+ACT8865 regulator
+-------------------
+
+Required properties:
+- compatible: "active-semi,act8865"
+- reg: I2C slave address
+
+Any standard regulator properties can be used to configure the single regulator.
+
+The valid names for regulators are:
+        DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
+
+Example:
+--------
