1 | Allwinner Sunxi NMI Controller |
| 2 | ============================== | |
| 3 | ||
| 4 | Required properties: | |
| 5 | ||
| 6 | - compatible : should be "allwinner,sun7i-a20-sc-nmi" or | |
| cc66ef3c | 7 | "allwinner,sun6i-a31-sc-nmi" or "allwinner,sun9i-a80-nmi" |

8 | - reg : Specifies base physical address and size of the registers. |
| 9 | - interrupt-controller : Identifies the node as an interrupt controller | |
| 10 | - #interrupt-cells : Specifies the number of cells needed to encode an | |
| 11 | interrupt source. The value shall be 2. The first cell is the IRQ number, the | |
| 12 | second cell the trigger type as defined in interrupt.txt in this directory. | |
| 13 | - interrupt-parent: Specifies the parent interrupt controller. | |
| 14 | - interrupts: Specifies the interrupt line (NMI) which is handled by | |
| 15 | the interrupt controller in the parent controller's notation. This value | |
| 16 | shall be the NMI. | |

| 18 | Example: | |
| 19 | ||
| 20 | sc-nmi-intc@01c00030 { | |
| 21 | compatible = "allwinner,sun7i-a20-sc-nmi"; | |
| 22 | interrupt-controller; | |
| 23 | #interrupt-cells = <2>; | |
| 24 | reg = <0x01c00030 0x0c>; | |
| 25 | interrupt-parent = <&gic>; | |
| 26 | interrupts = <0 0 4>; | |
| 27 | }; |
