NAME
 gscpcib — National Semiconductor Geode SC1100 PCI-ISA bridge with GPIO
SYNOPSIS
 gscpcib* at pci?
isa* at gscpcib?
gpio* at gscpcib?
DESCRIPTION
 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) 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.
 
HISTORY
 The gscpcib driver first appeared in OpenBSD 3.6 and NetBSD 4.0.
