+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Intel Atom E600 series LPC bridge and

+.Xr watchdog 4
+interface to the watchdog timer and may be used with
+.Xr watchdogd 8 .
+The watchdog timer can be configured via
+.Xr sysctl 8 .

+Once the watchdog timer resets the CPU, the driver reports it on the
+next boot displaying the ``reboot on timeout'' message in the dmesg.
+.Sh NOTES
+The maximum timeout value supported by the watchdog timer is 600
+seconds.
+.Sh SEE ALSO
+.Xr intro 4 ,

+.Xr pci 4 ,
+.Xr watchdog 4
+.Xr sysctl 8
+.Xr watchdogd 8
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 5.2 .
+.Sh AUTHORS
+The
+.Nm
+driver was written by
+.An Matt Dainty Aq matt@bodgit-n-scarper.com .
+.Sh BUGS
+Apart from the core

+.Xr watchdog 4
+interface, the driver doesn't support any other aspects of the hardware.
