NAME    [Toc]    [Back]

     nsclpcsio - National Semiconductor PC87366 LPC Super I/O

SYNOPSIS    [Toc]    [Back]

     nsclpcsio* at isa?

DESCRIPTION    [Toc]    [Back]

     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

     The  GPIO  logical  device provides 29 I/O pins which can be
     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:

HISTORY    [Toc]    [Back]

     The  nsclpcsio  driver first appeared in NetBSD 2.0, OpenBSD
support was
     added in OpenBSD 3.5.

AUTHORS    [Toc]    [Back]

     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
