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

32The chip supports only temperature measurement. The driver exports
33the temperature values via the following sysfs files:
34
35**temp[1-3]_input, temp[2-3]_fault, temp[2-3]_offset, update_interval**
