If you have only one interrupt controller, like here, you don't
need to refer to it _at all_ :-)
I think Linux requires that you do though. It might be a mistake on
our
part but heh ...
Linux doesn't require it; (old) Macs are like this, for example,
and that works fine. Oh and all Maple firmwares are like that as
well I think. Etc.
It works fine on old macs thanks to a quirk we enable in the mac code
iirc and old maple works thanks to mere luck with the fallback code we
have which reads things of PCI config space :-)
Don't rely on that.
It is standard OF. Let's fix the Linux code if that is needed (and I
don't
think it is, anyway).
OTOH, it's nice to use the interrupt mapping stuff in all new device
trees.
