^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) This driver implements support for Nuvoton W83773G temperature sensor
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) chip. This chip implements one local and two remote sensors.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) The chip also features offsets for the two remote sensors which get added to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) the input readings. The chip does all the scaling by itself and the driver
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) therefore reports true temperatures that don't need any user-space adjustments.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Temperature is measured in degrees Celsius.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The chip is wired over I2C/SMBus and specified over a temperature
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) range of -40 to +125 degrees Celsius (for local sensor) and -40 to +127
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) degrees Celsius (for remote sensors).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) Resolution for both the local and remote channels is 0.125 degree C.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) The chip supports only temperature measurement. The driver exports
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) the temperature values via the following sysfs files:
