Subject: [PATCH v4 0/2] Add device driver for APU2/APU3 GPIOs

Changes v2:
- Update SPDX short identifier
- Remove gpio-keys-polled device moved to arch/x86/platform
- Fix styling
- Use spinnlock only there where it is useful
- Removed useless output on driver load
- Do bit manipulation later not on IO
- Add additional GPIOs handling mpci2_reset and mpcie3_reset.
- Add name to GPIOs exported via sysfs

Changes v3:
- Add a new platform device for the frontpanel push button.
- Get global variables from the heap
- Fix errors/warnings generated by ./scripts/checkpatch.pl

Changes v4:
gpio-apu.c
- Move bit shifting out of spinnlock
- Change declaration of int to unsigned int
- Remove redundant blank line
- Use dmi table callback
- Remove noise
pcengines-apu-platform.c
- Move platform device to drivers/platform/x86
- Remove needless include
- Add dmi information so that this device is only present on APU2
  APU3 boards from PC Engines

Until now it was not possible to get more information to detect the
MMIO_BASE address from the ACPI subsystem.
