Say Y here if you want to support the built-in real time clock
of the HP SDC controller.
+config INPUT_GPIO_BUTTONS
+ tristate "Polled GPIO buttons interface"
+ depends on GENERIC_GPIO
+ select INPUT_POLLDEV
+ 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.
+
+ To compile this driver as a module, choose M here: the
+ module will be called gpio-buttons.
