  1. * OMAP Interrupt Controller
  2. OMAP2/3 are using a TI interrupt controller that can support several
  3. configurable number of interrupts.
  4. Main node required properties:
  5. - compatible : should be:
  6. "ti,omap2-intc"
  7. - interrupt-controller : Identifies the node as an interrupt controller
  8. - #interrupt-cells : Specifies the number of cells needed to encode an
  9. interrupt source. The type shall be a <u32> and the value shall be 1.
  10. The cell contains the interrupt number in the range [0-128].
  11. - ti,intc-size: Number of interrupts handled by the interrupt controller.
  12. - reg: physical base address and size of the intc registers map.
  13. Example:
  14. intc: interrupt-controller@1 {
  15. compatible = "ti,omap2-intc";
  16. interrupt-controller;
  17. #interrupt-cells = <1>;
  18. ti,intc-size = <96>;
  19. reg = <0x48200000 0x1000>;
  20. };
