Kernel-4.18.0-80.el8_snps,arc700-intc

• ARC700 incore Interrupt Controller

  The core interrupt controller provides 32 prioritised interrupts (2 levels)
  to ARC700 core.

Properties:

• compatible: “snps,arc700-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 0 to 31

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

Example:

intc: interrupt-controller {
    compatible = "snps,arc700-intc";
    interrupt-controller;
    #interrupt-cells = <1>;
};
