-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@...01800 {
-		compatible = "fsl,vf610-mscm-ir";
-		reg = <0x40001800 0x400>;
-		fsl,cpucfg = <&mscm_cpucfg>;
-		interrupt-controller;
-		#interrupt-cells = <2>;
-		interrupt-parent = <&intc>;
