The series adds event support to the Intel GPIO SCH driver. The hardware routes all events through GPE0 GPIO event.
I validated this on Intel Minnowboard (v1).
If somebody has different hardware with the same GPIO controller, I would appreciate additional testing.
Changes in v5: - added missed IRQ acknowledge callback (hence kernel Oops) - rewrite patch 2 completely from SCI to GPE hook
Changes in v4 (https://lore.kernel.org/linux-gpio/20210316162613.87710-1-andriy.shevchenko@linux.intel.com/T/#u): - 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
