1Allwinner Sunxi NMI Controller 2============================== 3 4Required properties: 5 6- compatible : should be "allwinner,sun7i-a20-sc-nmi" or 7 "allwinner,sun6i-a31-sc-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. 17 18Example: 19 20sc-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}; 28
