Honestly, I do not understand when and where to properly use
hierarchical irqdomain, even after Marc's talk at ELC-E.

Which is problematic since quite a few GPIO drivers now
need to use them.

I will review his slides, in the meantime I would say: whatever
Marc ACKs is fine with me. I trust this guy 100%. So I guess I
could ask that he ACK the entire chain of patches
from GIC->specialchip->GPIO.

Yours,
