gscpcib -- National Semiconductor Geode SC1100 PCI-ISA bridge with GPIO
gscpcib* at pci? isa* at gscpcib? gpio* at gscpcib?
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 pcib(4) function- ality, 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 manipu- late these pins from userland.
