WebIntroduction to the gpiolib sysfs. From Documentation/gpio.txt in v2.6.28: Platforms which use the "gpiolib" implementors framework may choose to configure a sysfs user interface to GPIOs. This is different from the debugfs interface, since it provides control over GPIO direction and value instead of just showing a gpio state summary.
