The
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.
