A framework for supporting various General Purpose Input/Output (GPIO)
devices. Such devices provide a set of pins that you can use to connect
for example leds to it.
The pins can be accessed either from userland through the /dev/gpio*
device files or from the kernel drivers. The latter is necessary
for implementing timing-sensitive things like i2c or 1-wire master
controller.
