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