* CRISv32 Interrupt Controller
Interrupt controller for the CRISv32 SoCs.
Main node required properties:
- compatible : should be:
"axis,crisv32-intc"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. The type shall be a <u32> and the value shall be 1.
- reg: physical base address and size of the intc registers map.
Example:
intc: interrupt-controller {
compatible = "axis,crisv32-intc";
reg = <0xb001c000 0x1000>;
interrupt-controller;
#interrupt-cells = <1>;
};
