NAME    [Toc]    [Back]

     gscpcib - National Semiconductor Geode SC1100 PCI-ISA bridge

SYNOPSIS    [Toc]    [Back]

     gscpcib* at pci? dev ? function ?
     isa* at gscpcib?
     gpio* at gscpcib?

DESCRIPTION    [Toc]    [Back]

     The  gscpcib  driver provides support for the National Semiconductor Geode
     SC1100 System-on-Chip PCI-ISA bridge.  This device is mostly
usual PCIISA
  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 allows to easily  manipulate pins from
     userland.
