Is this property valid for aic1? If not, you need:

else:
   not:
     required:
       - apple,event-reg

Thanks, I wasn't sure how to do this. Took me a second to realize how 
the logic works here, heh.

I tend to think you should just make this a separate document. There's
not a whole lot of sharing (compared to any other interrupt controller).

Good point. I just kind of defaulted to this way because the driver is 
the same (and does share a bunch), but indeed the binding doesn't really 
reflect any of that. I'll split it off into another document for v2. 
Might as well make the 4-argument interrupt form mandatory then (we use 
it for all DTs, even the current 1-die machines, on AICv2 SoCs; the 
driver can handle both but we might as well be stricter with the binding).

Simpler that way, so I'd support that.
