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: | |
34 | ||
b04f2f7d | 35 | **temp[1-3]_input, temp[2-3]_fault, temp[2-3]_offset, update_interval** |
