+PFUZE100 family of regulators
+
+Required properties:
+- compatible: "fsl,pfuze100"
+- reg: I2C slave address
+- regulators: This is the list of child nodes that specify the regulator
+  initialization data for defined regulators. Please refer to below doc
+  Documentation/devicetree/bindings/regulator/regulator.txt.
+
+  The valid names for regulators are:
+  sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
+
+Each regulator is defined using the standard binding for regulators.
+
+Example:
+
+        pmic: pfuze100@08 {
+                compatible = "fsl,pfuze100";
+                reg = <0x08>;
