  1. Freescale Vybrid Miscellaneous System Control - Interrupt Router
  2. The MSCM IP contains multiple sub modules, this binding describes the second
  3. block of registers which control the interrupt router. The interrupt router
  4. allows to configure the recipient of each peripheral interrupt. Furthermore
  5. it controls the directed processor interrupts. The module is available in all
  6. Vybrid SoC's but is only really useful in dual core configurations (VF6xx
  7. which comes with a Cortex-A5/Cortex-M4 combination).
  8. Required properties:
  9. - compatible: "fsl,vf610-mscm-ir"
  10. - reg: the register range of the MSCM Interrupt Router
  11. - fsl,cpucfg: The handle to the MSCM CPU configuration node, required
  12. to get the current CPU ID
  13. - interrupt-controller: Identifies the node as an interrupt controller
  14. - #interrupt-cells: Two cells, interrupt number and cells.
  15. The hardware interrupt number according to interrupt
  16. assignment of the interrupt router is required.
  17. Flags get passed only when using GIC as parent. Flags
  18. encoding as documented by the GIC bindings.
  19. - interrupt-parent: Should be the phandle for the interrupt controller of
  20. the CPU the device tree is intended to be used on. This
  21. is either the node of the GIC or NVIC controller.
  22. Example:
  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>;
