These chips +implement one local and up to one (TMP421, TMP441), up to two (TMP422, +TMP442) or up to three (TMP423) remote sensors. Temperature is measured +in degrees Celsius. The chips are wired over I2C/SMBus and specified +over a temperature range of -40 to +125 degrees Celsius. Resolution +for both the local and remote channels is 0.0625 degree C. + +The chips support only temperature measurement. The driver exports +the temperature values via the following sysfs files: + +**temp[1-4]_input** + +**temp[2-4]_fault** -- cgit v1.2.3
