In linux kernel since version 2.6.21.1 (release Date: 2007-04-27)
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.
To compile this driver as a module, choose M here: the
module will be called gpio_keys.
