Hi Dmitry,
GPIO descriptors are the preferred way over legacy GPIO numbers
nowadays. This patch series converts the gpio_keys driver to use GPIO
descriptors, like was done before for gpio_keys_polled.
As a bonus, support for ACPI based systems was added by making use of
the device property API. While this is not required for my use case, it
was easy to do, and keeps gpio_keys and gpio_keys_polled in sync.
This has been tested on a DT-based system only (r8a7791/koelsch).
Thanks for your comments!
