| Description
 | |
| -----------
 | |
| 
 | |
| This driver implements support for Nuvoton W83773G temperature sensor
 | |
| chip. This chip implements one local and two remote sensors.
 | |
| The chip also features offsets for the two remote sensors which get added to
 | |
| the input readings. The chip does all the scaling by itself and the driver
 | |
| therefore reports true temperatures that don't need any user-space adjustments.
 | |
| Temperature is measured in degrees Celsius.
 | |
| The chip is wired over I2C/SMBus and specified over a temperature
 | |
| range of -40 to +125 degrees Celsius (for local sensor) and -40 to +127
 | |
| degrees Celsius (for remote sensors).
 | |
| Resolution for both the local and remote channels is 0.125 degree C.
 | |
| 
 | |
| The chip supports only temperature measurement. The driver exports
 | |
| the temperature values via the following sysfs files:
 | |
| 
 | |
| temp[1-3]_input
 | |
| temp[2-3]_fault
 | |
| temp[2-3]_offset
 | |
| update_interval
