  2. ==============================
  3. Required properties:
  4. - compatible : should be "allwinner,sun7i-a20-sc-nmi" or
  5. "allwinner,sun6i-a31-sc-nmi"
  6. - reg : Specifies base physical address and size of the registers.
  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 value shall be 2. The first cell is the IRQ number, the

  11. - interrupt-parent: Specifies the parent interrupt controller.
  12. - interrupts: Specifies the interrupt line (NMI) which is handled by

  14. shall be the NMI.
  15. Example:
  16. sc-nmi-intc@01c00030 {
  17. compatible = "allwinner,sun7i-a20-sc-nmi";
  18. interrupt-controller;
  19. #interrupt-cells = <2>;
  20. reg = <0x01c00030 0x0c>;
  21. interrupt-parent = <&gic>;
  22. interrupts = <0 0 4>;
  23. };
