.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the
|
|
.Tn National Semiconductor
|
|
PC87366 LPC Super I/O.
|
|
The Super I/O incorporates several logical
|
|
devices, the following ones are supported: GPIO, VLM and TMS.
|
|
.Pp
|
|
The GPIO logical device provides 29 I/O pins which can be accessed
|
|
through the
|
|
.Xr gpio 4
|
|
framework.
|
|
The
|
|
.Xr gpioctl 8
|
|
program allows easy manipulation of the pins from userland.
|
|
.Pp
|
|
VLM and TMS logical devices provides hardware monitoring capabilities to
|
|
be used with the
|
|
.Xr envsys 4
|
|
API.
|
|
The following 17 monitoring sensors are available:

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).
