+Freescale i.MX IC Identification Module (IIM) device tree bindings
+
+This binding represents the IC Identification Module (IIM) found on
+i.MX25, i.MX27, i.MX31, i.MX35, i.MX51 and i.MX53 SoCs.
+
+Required properties:
+- compatible: should be one of
+ "fsl,imx25-iim", "fsl,imx27-iim",
+ "fsl,imx31-iim", "fsl,imx35-iim",
+ "fsl,imx51-iim", "fsl,imx53-iim",
+- reg: Should contain the register base and length.
+- interrupts: Should contain the interrupt for the IIM
+- clocks: Should contain a phandle pointing to the gated peripheral clock.
+
+Example:
+
+ iim: iim@63f98000 {
+ compatible = "fsl,imx53-iim", "fsl,imx27-iim";
+ reg = <0x63f98000 0x4000>;
+ interrupts = <69>;
+ clocks = <&clks IMX5_CLK_IIM_GATE>;
+ };
