From: Mario Limonciello <mario.limonciello@xxxxxxx> When soc-button-array looks up the GPIO to use it calls acpi_find_gpio() which will parse _CRS. acpi_find_gpio.cold (drivers/gpio/gpiolib-acpi-core.c:953) gpiod_find_and_request (drivers/gpio/gpiolib.c:4598 drivers/gpio/gpiolib.c:4625) gpiod_get_index (drivers/gpio/gpiolib.c:4877) The GPIO is setup basically, but the debounce information is discarded. The platform will assert what debounce should be in _CRS, so program it at the time it's available.
