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. ok deraadt@
