Input: gpio-keys - keyboard driver for GPIO buttons

Browse Source 
This is an interrupt-driven keyboard driver for simple buttons
connected directly to CPU GPIO lines of embedded ARM systems.
It supports pxa architectures and is used by a number of PDAs
and PocketPC phones in the handhelds.org kernel. Support for
other architectures, such as sa11xx and sc2410, will be added
once generic GPIO API is available.
