+Regulators included in the Freescale MC34708 PMIC
+
+Required properties:
+- compatible: "fsl,mc34708"
+- reg: I2C slave address
+
+
+Regulators subnode:
+-------------------
+This node contains children following the standard regulator binding format
+described in Documentation/devicetree/bindings/regulator/regulator.txt
+
+The allowed node names are:
+	Switchers:
+		sw1, sw2, sw3, sw4a, sw4b, sw5, swbst
+	LDOs:
+		vpll, vrefddr, vusb, vusb2, vdac, vgen1, vgen2
+
+The mode values are:
+	Switchers:
+		1 : Pulse Frequency Modulation (PFM) [for low loads]
+		2 : Auto
+		3 : Pulse Width Modulation (PWM) [for high loads]
+	LDOs:
+		1 : Low power
+		2 : Normal
+
+Optional properties:
+The input supply of regulators are the optional properties on the
+regulator node.
+
+- vinsw1-supply : phandle to input supply for sw1 regulator
+- vinsw2-supply : phandle to input supply for sw2 regulator
+- vinsw3-supply : phandle to input supply for sw3 regulator
+- vinsw4a-supply : phandle to input supply for sw4a regulator
+- vinsw4b-supply : phandle to input supply for sw4b regulator
+- vinsw5-supply : phandle to input supply for sw5 regulator
+- vinswbst-supply : phandle to input supply for swbst regulator
+- vinrefddr-supply : phandle to input supply for vrefddr regulator (/2)
