+Allwinner Sunxi NMI Controller
+==============================
+
+Required properties:
+
+- 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
+ interrupt source. The value shall be 2. The first cell is the IRQ number, the
+ second cell the trigger type as defined in interrupt.txt in this directory.
+- interrupt-parent: Specifies the parent interrupt controller.
+- interrupts: Specifies the interrupt line (NMI) which is handled by
+ the interrupt controller in the parent controller's notation. This value
+ 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>;
+};
