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, Linus Walleij
