+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, and i.MX6SX 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), followed by "syscon".
+- reg: Should contain the register base and length.
+- clocks: Should contain a phandle pointing to the gated peripheral clock.
+
+Example:
+
+	ocotp: ocotp@021bc000 {
+		compatible = "fsl,imx6q-ocotp", "syscon";
+		reg = <0x021bc000 0x4000>;
+		clocks = <&clks IMX6QDL_CLK_IIM>;
+	};
