GSCPCIB(4)           NetBSD/i386 Kernel Interfaces Manual           GSCPCIB(4)

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) 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.

HISTORY
     The gscpcib driver first appeared in OpenBSD 3.6 and NetBSD 4.0.

AUTHORS
     The gscpcib driver was written by Alexander Yurchenko
     <grange@openbsd.org> and was ported to NetBSD by Jared D. McNeill
     <jmcneill@NetBSD.org>.
