| - compatible : should be "allwinner,sun7i-a20-sc-nmi" or |
| "allwinner,sun6i-a31-sc-nmi" |
| - reg : Specifies base physical address and size of the registers. |
| - interrupt-controller : Identifies the node as an interrupt controller |
| - #interrupt-cells : Specifies the number of cells needed to encode an |

| |
| sc-nmi-intc@01c00030 { |
| compatible = "allwinner,sun7i-a20-sc-nmi"; |
| interrupt-controller; |
| #interrupt-cells = <2>; |
| reg = <0x01c00030 0x0c>; |
| interrupt-parent = <&gic>; |
| interrupts = <0 0 4>; |
| }; |
