gpio* 	at gcscpcib?
isa* 	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 OpenBSD 4.3 as glxpcib before being ported to NetBSD 5.0.
AUTHORS
