Required properties :

- compatible :

  - "fsl,imx23-ocotp" for i.MX23

  - "fsl,imx28-ocotp" for i.MX28

- #address-cells : Should be 1

- #size-cells : Should be 1

- reg : Address and length of OTP controller registers

- clocks : Should contain a reference to the hbus clock



= Data cells =

Are child nodes of mxs-ocotp, bindings of which as described in

bindings/nvmem/nvmem.txt



Example for i.MX28:



	ocotp: ocotp@8002c000 {

		compatible = "fsl,imx28-ocotp", "fsl,ocotp";

		#address-cells = <1>;

		#size-cells = <1>;

		reg = <0x8002c000 0x2000>;
