Kernel driver w83l786ng
=====================

Supported chips:
* Winbond W83L786NG/W83L786NR
Prefix: 'w83l786ng'
Addresses scanned: I2C 0x2e - 0x2f
Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L786NRNG09.pdf

Author: Kevin Lo <kevlo@kevlo.org>


Module Parameters
-----------------

* reset boolean
(default 0)
Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
behavior is no chip reset to preserve BIOS settings


Description
-----------

This driver implements support for Winbond W83L786NG/W83L786NR chips.

The driver implements two temperature sensors, two fan rotation speed
sensors, and three voltage sensors.

Temperatures are measured in degrees Celsius and measurement resolution is 1
degC for temp1 and temp2.

Fan rotation speeds are reported in RPM (rotations per minute). Fan readings
readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64
or 128 for fan 1/2) to give the readings more range or accuracy.

Voltage sensors (also known as IN sensors) report their values in millivolts.
An alarm is triggered if the voltage has crossed a programmable minimum
or maximum limit.

If you say yes here you get support for the Winbond W83L786NG
and W83L786NR sensor chips.

This driver can also be built as a module. If so, the module
will be called w83l786ng.
