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:

The nsclpcsio
device appeared in NetBSD
2.0.
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).
