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>;
};
