This chip implements one local and two remote sensors. 23*4882a593SmuzhiyunThe chip also features offsets for the two remote sensors which get added to 24*4882a593Smuzhiyunthe input readings. The chip does all the scaling by itself and the driver 25*4882a593Smuzhiyuntherefore reports true temperatures that don't need any user-space adjustments. 26*4882a593SmuzhiyunTemperature is measured in degrees Celsius. 27*4882a593SmuzhiyunThe chip is wired over I2C/SMBus and specified over a temperature 28*4882a593Smuzhiyunrange of -40 to +125 degrees Celsius (for local sensor) and -40 to +127 29*4882a593Smuzhiyundegrees Celsius (for remote sensors). 30*4882a593SmuzhiyunResolution for both the local and remote channels is 0.125 degree C. 31*4882a593Smuzhiyun 32*4882a593SmuzhiyunThe chip supports only temperature measurement. The driver exports 33*4882a593Smuzhiyunthe temperature values via the following sysfs files: 34*4882a593Smuzhiyun 35*4882a593Smuzhiyun**temp[1-3]_input, temp[2-3]_fault, temp[2-3]_offset, update_interval** 36
