I didn't read the specs but from what you described in
INTA and INTR bindings, does the flow of IRQs like below ?
Device IRQ(e.g USB) -->INTR-->INTA--->HOST IRQ controller(GIC)
The confusing part is aggregator and can multiplex as well
as grouping but seems like its event grouping or multiplexing
than actual device IRQ grouping or multi-plexsing.
What am I missing ?
