+Freescale Vybrid Miscellaneous System Control - Interrupt Router
+
+The MSCM IP contains multiple sub modules, this binding describes the second
+block of registers which control the interrupt router. The interrupt router
+allows to configure the recipient of each peripheral interrupt. Furthermore
+it controls the directed processor interrupts. The module is available in all
+Vybrid SoC's but is only really useful in dual core configurations (VF6xx
+which comes with a Cortex-A5/Cortex-M4 combination).
+
+Required properties:
+- compatible:		"fsl,vf610-mscm-ir"
+- reg:			the register range of the MSCM Interrupt Router
+- fsl,cpucfg:		The handle to the MSCM CPU configuration node, required
+			to get the current CPU ID
+- interrupt-controller:	Identifies the node as an interrupt controller
+- #interrupt-cells:	Two cells, interrupt number and cells.
+			The hardware interrupt number according to interrupt
+			assignment of the interrupt router is required.
+			Flags get passed only when using GIC as parent. Flags
+			encoding as documented by the GIC bindings.
+
+Example:
+	mscm_ir: interrupt-controller@40001800 {
+		compatible = "fsl,vf610-mscm-ir";
+		reg = <0x40001800 0x400>;
+		fsl,cpucfg = <&mscm_cpucfg>;
+		interrupt-controller;
+		#interrupt-cells = <2>;
+		interrupt-parent = <&intc>;
+	}
