Use IRQ flags instead of just 0 (here and further on). Also it might be
better to use interrupts-extended instead.

Yes, much better. BTW: are you sure that it's really IRQ_TYPE_NONE?

I believe it’s better to use the default type, which is the same as the
downstream approach. This way, it will be more stable.
