It is just a question where interrupt parent is listed. I have seen that
some SoCs are just setting up at one location for all IPs.
I remember some discussions that some properties don't need to be
documented again and again. That's why the question is if they are
really needed to be documented in the binding doc because it is just
documentation duplication in every binding document.

Definitely if you miss it in the binding doc, feel free to send the
patch and update it.

Thanks,
Michal
