.Dd $Mdocdate: December 23 2007 $ .Dt NSCLPCSIO 4 .Os .Sh NAME .Nm nsclpcsio .Nd National Semiconductor PC87366 LPC Super I/O with GPIO .Sh SYNOPSIS .Cd "nsclpcsio* at isa?" .Cd "gpio* at nsclpcsio?" .Sh DESCRIPTION The .Nm driver provides support for the National Semiconductor PC87366 LPC Super I/O. The Super I/O module incorporates several logical devices, the following ones are supported: GPIO, VLM and TMS.
p 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.
p VLM and TMS logical devices provides hardware monitoring capabilities to be used with the .Xr sysctl 8 interface. The following 17 monitoring sensors are available: l -column "Sensor" "Units" "Typical" -offset indent t Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use" t Li "TSENS1" Ta "uK" Ta "Remote diode" t Li "TSENS2" Ta "uK" Ta "Remote diode" t Li "TNSC" Ta "uK" Ta "Local diode" t Li "VSENS0" Ta "uV DC" Ta "External source" t Li "VSENS1" Ta "uV DC" Ta "External source" t Li "VSENS2" Ta "uV DC" Ta "External source" t Li "VSENS3" Ta "uV DC" Ta "External source" t Li "VSENS4" Ta "uV DC" Ta "External source" t Li "VSENS5" Ta "uV DC" Ta "External source" t Li "VSENS6" Ta "uV DC" Ta "External source" t Li "VSB" Ta "uV DC" Ta "VSB" t Li "VDD" Ta "uV DC" Ta "VDD" t Li "VBAT" Ta "uV DC" Ta "VBAT" t Li "AVDD" Ta "uV DC" Ta "AVDD" t Li "TS1" Ta "uV DC" Ta "Thermistor" t Li "TS2" Ta "uV DC" Ta "Thermistor" t Li "TS3" Ta "uV DC" Ta "Thermistor" .El .Sh SEE ALSO .Xr gpio 4 , .Xr isa 4 , .Xr gpioctl 8 , .Xr sensorsd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm driver first appeared in .Nx 2.0 , .Ox support was added in .Ox 3.5 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Matthias Drochner Aq Mt drochner@netbsd.org for .Nx and then ported to .Ox 3.5 by .An Markus Friedl Aq Mt markus@openbsd.org . .Tn GPIO support was added in .Ox 3.6 by .An Alexander Yurchenko Aq Mt grange@openbsd.org .
