-.Nd AMD Elan SC520 System Controller with watchdog timer and GPIO
-.Sh SYNOPSIS
-.Cd "elansc* at pci?"
-.Cd "gpio* at elansc?"
-.Sh DESCRIPTION
-The
-.Nm
-driver supports the system controller of the AMD Elan SC520 microcontroller.
-The SC520 consists of an AMD Am5x86 processor core, integrated PCI host
-controller, and several standard on-chip devices, such as NS16550-compatible
-UARTs, real-time clock, and timers.
-.Pp
-The Elan SC520 also provides several special on-chip devices.
-The following are supported by the
-.Nm
-driver:
-.Bl -bullet
-.It
-Watchdog timer.
-The watchdog timer may be configured for a 1 second, 2 second, 4 second,
-8 second, 16 second, or 32 second expiration period.
-.It
-Programmable Input/Output.
-The SC520 microcontroller supports 32 programmable I/O signals (PIOs)
-that can be used on the system board to monitor signals or control devices
-that are not handled by the other functions in the SC520 microcontroller.
-These signals can be programmed to be inputs or to be driven out
-.Dq high
-or
-.Dq low
-as outputs.
-Pins can be accessed through the
-.Xr gpio 4
-framework.
-The
-.Xr gpioctl 8
-program allows easy manipulation of pins from userland.

-.Sh HISTORY
-Support for the

-was added in
-.Ox 3.3 .
-PIO function support appeared in
-.Ox 3.6 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-driver was written by
-.An Jason R. Thorpe Aq Mt thorpej@netbsd.org .
-.An Jasper Wallace
-provided the work-around for a hardware bug related to the watchdog timer
-in some steppings of the SC520 CPU.
-.An Alexander Yurchenko Aq Mt grange@openbsd.org
-added support for the PIO function.
