| 18 | Description |
| 19 | ----------- |
| 20 | |
| 21 | This driver implements support for Nuvoton W83773G temperature sensor |
| 22 | chip. This chip implements one local and two remote sensors. |
| 23 | The chip also features offsets for the two remote sensors which get added to |
| 24 | the input readings. The chip does all the scaling by itself and the driver |
| 25 | therefore reports true temperatures that don't need any user-space adjustments. |
| 26 | Temperature is measured in degrees Celsius. |
| 27 | The chip is wired over I2C/SMBus and specified over a temperature |
| 28 | range of -40 to +125 degrees Celsius (for local sensor) and -40 to +127 |
| 29 | degrees Celsius (for remote sensors). |
| 30 | Resolution for both the local and remote channels is 0.125 degree C. |
| 31 | |
| 32 | The chip supports only temperature measurement. The driver exports |
| 33 | the temperature values via the following sysfs files: |
