What I need to understand for hierarchical interrupt controllers
on GPIO is what I can pull into the gpio library. I am working
to extract some code from drivers/gpio/gpio-ixp4xx.c
to make generic simple hierarchical domain support available,
and Lina is working on generalizing some stuff.
But these complex domain operations in the STM32 seem
to be some special beast.
