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

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.

The gcscpcib
driver first appeared in
OpenBSD 4.3 as glxpcib
before being ported to NetBSD 5.0.
The gcscpcib
driver was written by
Michael Shalayeff and Yojiro
UO. The GPIO parts were added by Marc Balmer
<marc@msys.ch>.
