| Allwinner Sunxi NMI Controller | |
| ============================== | |
| Required properties: | |
| - compatible : should be one of the following: | |
| - "allwinner,sun7i-a20-sc-nmi" | |
| - "allwinner,sun6i-a31-sc-nmi" (deprecated) | |
| - "allwinner,sun6i-a31-r-intc" | |
| - "allwinner,sun9i-a80-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 | |
| interrupt source. The value shall be 2. The first cell is the IRQ number, the | |

| shall be the NMI. | |
| Example: | |
| 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>; | |
| }; |
