The nsclpcsio driver provides support for the National Semiconductor
PC87366 LPC Super I/O. The Super I/O module incorporates
several logical
devices, the following ones are supported: GPIO, VLM and
TMS.
The GPIO logical device provides 29 I/O pins which can be
accessed
through the gpio(4) framework. The gpioctl(8) program allows easy manipulation
of the pins from userland.
VLM and TMS logical devices provides hardware monitoring capabilities to
be used with the sysctl(8) interface. The following 17 monitoring sensors
are available:

The nsclpcsio driver first appeared in NetBSD 2.0, OpenBSD
support was
added in OpenBSD 3.5.
The nsclpcsio driver was written by Matthias Drochner
<drochner@netbsd.org> for NetBSD and then ported to OpenBSD
3.5 by
Markus Friedl <markus@openbsd.org>. GPIO suppport was added
in OpenBSD
3.6 by
Alexander Yurchenko <grange@openbsd.org>.
OpenBSD 3.6 January 5, 2004
