if INPUT_KEYBOARD config KEYBOARD_TIMED_GPIO tristate "Timed GPIO Buttons" depends on GPIOLIB help This driver implements support for buttons connected to GPIO pins of various CPUs (and some other chips). Key presses are timed and can send different key codes depending on time it was pressed. Say Y here if your device has buttons connected directly to such GPIO pins. Your board-specific setup logic must also provide a platform device, with configuration data saying which GPIOs are used. To compile this driver as a module, choose M here: the module will be called gpio_timed_keys. endif
