Kernel-4.18.0-80.el8_snps,archs-intc

  • ARC-HS incore Interrupt Controller (Provided by cores implementing ARCv2 ISA)

Properties:

  • compatible: “snps,archs-intc”

  • interrupt-controller: This is an interrupt controller.

  • #interrupt-cells: Must be <1>.

    Single Cell “interrupts” property of a device specifies the IRQ number
    between 16 to 256

    intc accessed via the special ARC AUX register interface, hence “reg” property
    is not specified.

Example:

intc: interrupt-controller {
    compatible = "snps,archs-intc";
    interrupt-controller;
    #interrupt-cells = <1>;
    interrupts = <16 17 18 19 20 21 22 23 24 25>;
};
