9.Sh NAME
10.Nm gcscpcib
11.Nd "AMD CS553[56] PCI-ISA bridge with timecounter, watchdog timer, and GPIO"
12.Sh SYNOPSIS
13.Cd "gcscpcib* at pci? dev ? function ?"
14.Cd "gpio* 	at gcscpcib?"
15.Cd "isa* 	at gcscpcib?"
16.Sh DESCRIPTION
17The
18.Nm
19driver provides support for the AMD Geode CS5535 and CS5536 Companion chip.
20This device contains a number of components, including a PCI-ISA bridge.
21Besides the core functionality, the
22.Nm
23driver implements a 32-bit 3.5 MHz timecounter, a watchdog timer device,
24and a GPIO device. The watchdog timer may be configured via the
25.Xr wdogctl 8
26utility and the GPIO pins can be manipulated via the
27.Xr gpioctl 8
28utility.
