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
