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>;
|
|
};
