IRQ domains are a Linux internal detail, and their description doesn't
belong in the DT. So this property does not look like it should be
described in the DT.

I don't see a description of any relationship between devices here, so
it's not clear to me what this property is intended to imply.

Why do you think you need this?

Thanks,
Mark.
