Subject: [PATCH v5 0/2] gpio: sch: Interrupt support
Date: Wed, 17 Mar 2021 17:19:26 +0200	[thread overview]
Message-ID: <20210317151928.41544-1-andriy.shevchenko@linux.intel.com> (raw)

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
