| 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 |
| 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. |
