Allwinner Sunxi Interrupt Controller
Required properties:
- compatible : should be "allwinner,sun4i-ic"
- 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 1.
For the valid interrupt sources for your SoC, see the documentation in
sunxi/<soc>.txt
Example:
intc: interrupt-controller {
compatible = "allwinner,sun4i-ic";
reg = <0x01c20400 0x400>;
interrupt-controller;
#interrupt-cells = <2>;
};
