These chips implement one local 26and up to one (TMP421), up to two (TMP422) or up to three (TMP423) 27remote sensors. Temperature is measured in degrees Celsius. The chips 28are wired over I2C/SMBus and specified over a temperature range of -40 29to +125 degrees Celsius. Resolution for both the local and remote 30channels is 0.0625 degree C. 31 32The chips support only temperature measurement. The driver exports 33the temperature values via the following sysfs files: 34 35temp[1-4]_input 36temp[2-4]_fault 37
