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 |
