   4 Required properties:
   5
   6 - compatible : should be one of the following:
   7   - "allwinner,sun7i-a20-sc-nmi"
   8   - "allwinner,sun6i-a31-sc-nmi" (deprecated)
   9   - "allwinner,sun6i-a31-r-intc"
  10   - "allwinner,sun9i-a80-nmi"
  11 - reg : Specifies base physical address and size of the registers.
  12 - interrupt-controller : Identifies the node as an interrupt controller
  13 - #interrupt-cells : Specifies the number of cells needed to encode an
  14   interrupt source. The value shall be 2. The first cell is the IRQ number, the
  15   second cell the trigger type as defined in interrupt.txt in this directory.
  16 - interrupt-parent: Specifies the parent interrupt controller.
  17 - interrupts: Specifies the interrupt line (NMI) which is handled by

  24         compatible = "allwinner,sun7i-a20-sc-nmi";
  25         interrupt-controller;
  26         #interrupt-cells = <2>;
  27         reg = <0x01c00030 0x0c>;
  28         interrupt-parent = <&gic>;
  29         interrupts = <0 0 4>;
