The Loongson Extend I/O interrupt controller can be referenced in interrupt-map properties (e.g. in arch/loongarch/boot/dts/loongson-2k0500.dtsi), thus the nodes should have address-cells property.

|
|
This interrupt controller is found on the Loongson-3 family chips and
|
|
Loongson-2K series chips and is used to distribute interrupts directly to
|
|
individual cores without forwarding them through the HT's interrupt line.
