Subject: [PATCH v3 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

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