.Dd November 9, 2007 .Dt NSCLPCSIO 4 .Os .Sh NAME .Nm nsclpcsio .Nd National Semiconductor PC87366 LPC Super I/O .Sh SYNOPSIS .Cd "nsclpcsio* at isa?" .Cd "gpio* at nsclpcsio?" .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.
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 envsys 4 API. 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 envsys 4 , .Xr envstat 8 .Sh HISTORY The .Nm device appeared in .Nx 2.0 . .Sh 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).
