-* ARC-HS Interrupt Distribution Unit
-
- This optional 2nd level interrupt controller can be used in SMP configurations for
- dynamic IRQ routing, load balancing of common/external IRQs towards core intc.
-
-Properties:
-
-- compatible: "snps,archs-idu-intc"
-- interrupt-controller: This is an interrupt controller.
-- interrupt-parent: <reference to parent core intc>
-- #interrupt-cells: Must be <2>.
-- interrupts: <...> specifies the upstream core irqs
-
- First cell specifies the "common" IRQ from peripheral to IDU
- Second cell specifies the irq distribution mode to cores
- 0=Round Robin; 1=cpu0, 2=cpu1, 4=cpu2, 8=cpu3
-
- intc accessed via the special ARC AUX register interface, hence "reg" property
- is not specified.
-
-Example:
- core_intc: core-interrupt-controller {
- compatible = "snps,archs-intc";
- interrupt-controller;
- #interrupt-cells = <1>;
- };
-
- idu_intc: idu-interrupt-controller {
- compatible = "snps,archs-idu-intc";
- interrupt-controller;
- interrupt-parent = <&core_intc>;
-
- /*
- * <hwirq distribution>
- * distribution: 0=RR; 1=cpu0, 2=cpu1, 4=cpu2, 8=cpu3
- */
- #interrupt-cells = <2>;
-
- /* upstream core irqs: downstream these are "COMMON" irq 0,1.. */
- interrupts = <24 25 26 27 28 29 30 31>;
- };
-
- some_device: serial@c0fc1000 {
- interrupt-parent = <&idu_intc>;
- interrupts = <0 0>; /* upstream idu IRQ #24, Round Robin */
- };

-* ARC700 incore Interrupt Controller
