+Freescale Vybrid Miscellaneous System Control - CPU Configuration
+
+The MSCM IP contains multiple sub modules, this binding describes the first
+block of registers which contains CPU configuration information.
+
+Required properties:
+- compatible: "fsl,vf610-mscm-cpucfg", "syscon"
+- reg: the register range of the MSCM CPU configuration registers
+
+Example:
+ mscm_cpucfg: cpucfg@40001000 {
+ compatible = "fsl,vf610-mscm-cpucfg", "syscon";
+ reg = <0x40001000 0x800>;

+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.
+- interrupt-parent: Should be the phandle for the interrupt controller of
+ the CPU the device tree is intended to be used on. This
+ is either the node of the GIC or NVIC controller.
+
+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>;
+ }
