At your convenience please look at the debounce function a bit closer because I think there is a bug/unpredictable behavior: IIUC the whole bank/block of GPIOs share the same debounce timer setting, and it is currently handled in a "last caller wins" manner, so if the different GPIOs in the bank has different debounce settings, the call order decides what debounce time is used across all of them. In drivers/gpio/gpio-ftgpio.c function ftgpio_gpio_set_config() I simply reject a dounce time setting different from the currently configured if any GPIOs are currently using the deounce feature. (It's the semantic I came up with but maybe there are other ideas here.) Yours, Linus Walleij
