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:

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).
