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>;
	};
