Can this be described in firmware?

Hi, Russell,

I'm not sure, could you explain what you mean?

Modern systems describe the IRQ triggering in firmware for the OS
such as DT. Does your implementation have any firmware that can
do this kind of description for you (e.g. DT, ACPI?)

Hi, Russell,

I see. I think I can get this from DT.

Thanks,
Feiyang
