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.shevche...@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.kis...@siemens.com/T/#u): - split-up of the irq enabling patch as requested by Andy Andy Shevchenko (1): gpio: sch: Hook into ACPI GPE handler to catch GPIO edge events Jan Kiszka (1): gpio: sch: Add edge event support drivers/gpio/gpio-sch.c | 196 ++++++++++++++++++++++++++++++++++++++-- 1 file changed, 188 insertions(+), 8 deletions(-) -- 2.30.2
