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 manipu- lation 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 SEE ALSO
envsys(4), envstat(8) 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). BSD

gpiolock -- support for multi-position keylocks attached to GPIO pins SYNOPSIS
gpiolock* at gpio? offset ? mask ? gpiolock* at gpio? DESCRIPTION
The gpiolock driver allows connecting of multi-position keylocks over GPIO pins. The keylock driver registers with an in-kernel keylock sup- porting system and provides kauth(9) support through an experimental security model. The keylock state can be queried using the hw.keylock sysctl variables. Only locks with 2-4 positions are currently supported. The pin number is specified in the kernel configuration with the offset locator. The mask locator denotes the pins used for the lock (minimum 2, maximum 4 pins are used). The offset and mask can also be specified when gpiolock is attached at runtime using the GPIOATTACH ioctl(2) on the gpio(4) device. SEE ALSO
gpio(4), intro(4) HISTORY
The gpiolock driver first appeared in NetBSD 6.0. AUTHORS
The gpiolock driver was written by Marc Balmer <>. BSD
