This isn't quite the same as "how to handle the VIA quirks correctly",
but it does seem like the IRQ API should probably have a call to get
the IRQ trigger mode, just like it has ways to set it. I've seen
drivers that need to try multiple trigger modes before they find one
that will work on the target platform.
The actual details of _how_ that trigger mode is set -- APIC, PIC and
so on for x86; or other IRQ controllers on other hardware -- should
not matter to drivers, since they're platform-specific. The quirk
handling code is platform-specific though, and might care.
