0018 Description
0019 -----------
0020
0021 This driver implements support for Nuvoton W83773G temperature sensor
0022 chip. This chip implements one local and two remote sensors.
0023 The chip also features offsets for the two remote sensors which get added to
0024 the input readings. The chip does all the scaling by itself and the driver
0025 therefore reports true temperatures that don't need any user-space adjustments.
0026 Temperature is measured in degrees Celsius.
0027 The chip is wired over I2C/SMBus and specified over a temperature
0028 range of -40 to +125 degrees Celsius (for local sensor) and -40 to +127
0029 degrees Celsius (for remote sensors).
0030 Resolution for both the local and remote channels is 0.125 degree C.
0031
0032 The chip supports only temperature measurement. The driver exports
0033 the temperature values via the following sysfs files:
0034
0035 **temp[1-3]_input, temp[2-3]_fault, temp[2-3]_offset, update_interval**
