+Actions Semi ATC260X PMIC
+
+The atc260x family current members:
+atc2609a
+
+Required properties:
+- compatible: "actions,atc2609a"
+- reg: I2C slave address
+- interrupts: The interrupt line the IRQ signal for the device is connected to
+
+Optional ATC2609A properties:
+- vcc0-supply:  The input supply for DCDC_REG0
+- vcc1-supply:  The input supply for DCDC_REG1
+- vcc2-supply:  The input supply for DCDC_REG2
+- vcc3-supply:  The input supply for DCDC_REG3
+- vcc4-supply:  The input supply for DCDC_REG4
+- vcc5-supply:  The input supply for LDO_REG0
+- vcc6-supply:  The input supply for LDO_REG1
+- vcc7-supply:  The input supply for LDO_REG2
+- vcc8-supply:  The input supply for LDO_REG3
+- vcc9-supply:  The input supply for LDO_REG4
+- vcc10-supply:  The input supply for LDO_REG5
+- vcc11-supply:  The input supply for LDO_REG6
+- vcc12-supply: The input supply for LDO_REG7
+- vcc13-supply: The input supply for LDO_REG8
+- vcc14-supply: The input supply for LDO_REG9
+
+Regulators: All the regulators of ATC260X to be instantiated shall be
+listed in a child node named 'regulators'. Each regulator is represented
+by a child node of the 'regulators' node.
+
+	regulator-name {
+		/* standard regulator bindings here */
+	};
+
+Following regulators of the ATC2609A PMIC regulators are supported. Note that
+the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
+number as described in ATC2609A datasheet.
+
+	- DCDC_REGn
+		- valid values for n are 0 to 4.
+	- LDO_REGn
+		- valid values for n are 0 to 9
+
+Standard regulator bindings are used inside regulator subnodes. Check
+  Documentation/devicetree/bindings/regulator/regulator.txt
+for more details
