+On-Chip OTP Memory for Freescale Vybrid
+
+Required Properties:
+  compatible:
+  - "fsl,vf610-ocotp" for VF5xx/VF6xx
+  #address-cells : Should be 1
+  #size-cells : Should be 1
+  reg : Address and length of OTP controller and fuse map registers
+  clocks : ipg clock we associate with the OCOTP peripheral
+
+Example for Vybrid VF5xx/VF6xx:
+
+       ocotp: ocotp@400a5000 {
+               compatible = "fsl,vf610-ocotp";
+               #address-cells = <1>;
+               #size-cells = <1>;
+               reg = <0x400a5000 0xCF0>;
+               clocks = <&clks VF610_CLK_OCOTP>;
+       };
