  1. * Central Interrupt Unit v3
  2. Properties:
  3. - compatible: "cavium,octeon-7890-ciu3"
  4. Compatibility with 78XX and 73XX SOCs.
  5. - interrupt-controller: This is an interrupt controller.
  6. - reg: The base address of the CIU's register bank.
  7. - #interrupt-cells: Must be <2>. The first cell is source number.
  8. The second cell indicates the triggering semantics, and may have a
  9. value of either 4 for level semantics, or 1 for edge semantics.
  10. Example:
  11. interrupt-controller@1010000000000 {
  12. compatible = "cavium,octeon-7890-ciu3";
  13. interrupt-controller;
  14. /* Interrupts are specified by two parts:
  15. * 1) Source number (20 significant bits)
  16. * 2) Trigger type: (4 == level, 1 == edge)
  17. */
  18. #address-cells = <0>;
  19. #interrupt-cells = <2>;
  20. reg = <0x10100 0x00000000 0x0 0xb0000000>;
