The gscpcib driver provides support for the National Semiconductor Geode
SC1100 System-on-Chip PCI-ISA bridge. This device is mostly
bridge but with some additional sub-devices. Besides
pcib(4) 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
framework. The gpioctl(8) program allows to easily manipulate pins from
gpio(4), intro(4), isa(4), pci(4), pcib(4), gpioctl(8)
The gscpcib driver first appeared in OpenBSD 3.6.
The gscpcib driver was written by Alexander Yurchenko
OpenBSD 3.6 May 3, 2004
