NAME
     gcscpcib -- AMD CS553[56] PCI-ISA bridge with timecounter, watchdog
     timer, and GPIO

SYNOPSIS
     gcscpcib* at pci? dev ? function ?
     gpio*     at gcscpcib?

DESCRIPTION
     The gcscpcib driver provides support for the AMD Geode CS5535 and CS5536
     Companion chip.  This device contains a number of components, including a
     PCI-ISA bridge.  Besides the core functionality, the gcscpcib driver
     implements a 32-bit 3.5 MHz timecounter, a watchdog timer device, and a
     GPIO device. The watchdog timer may be configured via the wdogctl(8)
     utility and the GPIO pins can be manipulated via the gpioctl(8) utility.

HISTORY
     The gcscpcib driver first appeared in NetBSD 5.0.

AUTHORS
     The gcscpcib driver was written by Michael Shalayeff and Yojiro UO.  The
     GPIO parts were added by Marc Balmer <mbalmer@openbsd.org>.
