gscpcib driver provides support for
the National Semiconductor Geode SC1100 System-on-Chip PCI-ISA bridge. This
device is a PCI-ISA bridge, but with some additional sub-devices. Besides
the core functionality, the
gscpcib driver provides
support for the GPIO interface of this device.
The device has 64 I/O pins which can be accessed through the gpio(4) framework. The gpioctl(8) program provides a convenient way to manipulate these pins from userland.
