# # Input device configuration # menu "Input device support" config KEYBOARD_GPIO bool "GPIO Buttons" depends on GENERIC_GPIO help This driver implements support for buttons connected to GPIO pins of various CPUs (and some other chips). 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. config KEYBOARD_IMX_KEYPAD bool "IMX Keypad" depends on ARCH_IMX select POLLER help This driver implements support for buttons connected to the IMX keypad matrix. Say Y here if your device has buttons connected to the IMX keypad matrix. Your board-specific setup logic must also provide a 'matrix_keymap_data' structure, defining the used keys. endmenu
