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
VSENS0	uV DC	External source
VSENS1	uV DC	External source
VSENS2	uV DC	External source
VSENS3	uV DC	External source
VSENS4	uV DC	External source
VSENS5	uV DC	External source
VSENS6	uV DC	External source
VSB	uV DC	VSB
VDD	uV DC	VDD
VBAT	uV DC	VBAT
AVDD	uV DC	AVDD
TS1	uV DC	Thermistor
TS2	uV DC	Thermistor
TS3	uV DC	Thermistor

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).
