NAME

     gscpcib -- National Semiconductor Geode SC1100 PCI-ISA bridge


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) 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.
