These chips 34 implement one local and up to one (TMP421, TMP441), up to two (TMP422, 35 TMP442) or up to three (TMP423) remote sensors. Temperature is measured 36 in degrees Celsius. The chips are wired over I2C/SMBus and specified 37 over a temperature range of -40 to +125 degrees Celsius. Resolution 38 for both the local and remote channels is 0.0625 degree C. 39 40 The chips support only temperature measurement. The driver exports 41 the temperature values via the following sysfs files: 42 43 temp[1-4]_input 44 temp[2-4]_fault
