1Freescale Vybrid Miscellaneous System Control - Interrupt Router 2 3The MSCM IP contains multiple sub modules, this binding describes the second 4block of registers which control the interrupt router. The interrupt router 5allows to configure the recipient of each peripheral interrupt. Furthermore 6it controls the directed processor interrupts. The module is available in all 7Vybrid SoC's but is only really useful in dual core configurations (VF6xx 8which comes with a Cortex-A5/Cortex-M4 combination). 9 10Required properties: 11- compatible: "fsl,vf610-mscm-ir" 12- reg: the register range of the MSCM Interrupt Router 13- fsl,cpucfg: The handle to the MSCM CPU configuration node, required 14 to get the current CPU ID 15- interrupt-controller: Identifies the node as an interrupt controller 16- #interrupt-cells: Two cells, interrupt number and cells. 17 The hardware interrupt number according to interrupt 18 assignment of the interrupt router is required. 19 Flags get passed only when using GIC as parent. Flags 20 encoding as documented by the GIC bindings. 21 22Example: 23 mscm_ir: interrupt-controller@40001800 { 24 compatible = "fsl,vf610-mscm-ir"; 25 reg = <0x40001800 0x400>; 26 fsl,cpucfg = <&mscm_cpucfg>; 27 interrupt-controller; 28 #interrupt-cells = <2>; 29 interrupt-parent = <&intc>; 30 }
