Input: gpio-keys - keyboard driver for GPIO buttons
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.
