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>;
};
