NAME
     nsclpcsio -- National Semiconductor PC87366 LPC Super I/O

SYNOPSIS
     nsclpcsio* at isa?
     gpio* at nsclpcsio?

DESCRIPTION
     The nsclpcsio driver provides support for the National Semiconductor PC87366 LPC Super I/O.
     The Super I/O 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
     envsys(4) API.  The following 17 monitoring sensors are available:

	   Sensor    Units    Typical Use
	   TSENS1    uK       Remote diode
	   TSENS2    uK       Remote diode
	   TNSC      uK       Local diode

HISTORY
     The nsclpcsio device appeared in NetBSD 2.0.

BUGS
     The chip decodes address ranges which are not obvious and cannot be controlled by the kernel
     configuration file (must be set up by the BIOS).
