+Freescale i.MX6 On-Chip OTP Controller (OCOTP) device tree bindings
+
+This binding represents the on-chip eFuse OTP controller found on
+i.MX6Q/D, i.MX6DL/S, i.MX6SL, i.MX6SX, i.MX6UL and i.MX6SLL SoCs.
+
+Required properties:
+- compatible: should be one of
+	"fsl,imx6q-ocotp" (i.MX6Q/D/DL/S),
+	"fsl,imx6sl-ocotp" (i.MX6SL), or
+	"fsl,imx6sx-ocotp" (i.MX6SX),
+	"fsl,imx6ul-ocotp" (i.MX6UL),
+	"fsl,imx7d-ocotp" (i.MX7D/S),
+	"fsl,imx6sll-ocotp" (i.MX6SLL),
+	followed by "syscon".
+- #address-cells : Should be 1
+- #size-cells : Should be 1
+- reg: Should contain the register base and length.
+- clocks: Should contain a phandle pointing to the gated peripheral clock.
+
+Optional properties:
+- read-only: disable write access
+
+Optional Child nodes:
+
+- Data cells of ocotp:
+  Detailed bindings are described in bindings/nvmem/nvmem.txt
+
+Example:
+	ocotp: ocotp@21bc000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		compatible = "fsl,imx6sx-ocotp", "syscon";
+		reg = <0x021bc000 0x4000>;
+		clocks = <&clks IMX6SX_CLK_OCOTP>;
+
+		tempmon_calib: calib@38 {
+			reg = <0x38 4>;
+		};
+
+		tempmon_temp_grade: temp-grade@20 {
+			reg = <0x20 4>;
+		};
+	};
