Subject: [PATCH v4 0/2] gpio: sch: Interrupt support

I'm now struggling to test this on Intel Minnowboard (v1), but it seems not
working and it's only one possible pin to test, so I have to take soldering
iron in my hands and do some hardware hacks to test. Meanwhile I sent this in
order to Jan to test on his side that everything is working on their platform.

Changes in v4:
- turned to GPIO core infrastructure of IRQ chip instantiation (Linus)
- converted IRQ callbacks to use better APIs
- use handle_bad_irq() as default handler and now I know why, see
  eb441337c714 ("gpio: pca953x: Set IRQ type when handle Intel Galileo Gen 2")
  for the real example what happens if it's preset to something meaningful
- fixed remove stage (we have to remove SCI handler, which wasn't done in v3)

Changes in v3 (https://lore.kernel.org/linux-gpio/cover.1574277614.git.jan.kiszka@siemens.com/T/#u):
 - split-up of the irq enabling patch as requested by Andy

Jan Kiszka (2):
  gpio: sch: Add edge event support
  gpio: sch: Hook into ACPI SCI handler to catch GPIO edge events
