+ 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.

|
|
+ module will be called gpio-buttons.
