Hallo Phil, thank you for your answer.

I've ran into this problem before myself. As far as I could determine there was no way to delay the enabling of the irq.
Did you solve the issue at that time? If so, how?

There's probably enough information in the dt to determine this by searching for all the devices using that irq.

An approach would be to create an intermediary irq chip device. (Something that models an AND /OR gate for example) The driver for which could be setup to delay registering the irq until all irq sources have registered.

This would keep the code separate for the core irq library I think...
This proxy sounds like an interesting idea. I will try to see what can be done in this regard.

Best regards
