These chips55implement one local and up to one (TMP421, TMP441), up to two (TMP422,56TMP442) or up to three (TMP423) remote sensors. Temperature is measured57in degrees Celsius. The chips are wired over I2C/SMBus and specified58over a temperature range of -40 to +125 degrees Celsius. Resolution59for both the local and remote channels is 0.0625 degree C.60 61The chips support only temperature measurement. The driver exports62the temperature values via the following sysfs files:63 64**temp[1-4]_input**65 66**temp[2-4]_fault**67 68Each sensor can be individually disabled via Devicetree or from sysfs69via:70 71**temp[1-4]_enable**72 73If labels were specified in Devicetree, additional sysfs files will74be present:75 76**temp[1-4]_label**77
