29Description
30-----------
31
32This driver implements support for Texas Instruments TMP421, TMP422,
33TMP423, TMP441, and TMP442 temperature sensor chips. These chips
34implement one local and up to one (TMP421, TMP441), up to two (TMP422,
35TMP442) or up to three (TMP423) remote sensors. Temperature is measured
36in degrees Celsius. The chips are wired over I2C/SMBus and specified
37over a temperature range of -40 to +125 degrees Celsius. Resolution
38for both the local and remote channels is 0.0625 degree C.

40The chips support only temperature measurement. The driver exports
41the temperature values via the following sysfs files:
42
43temp[1-4]_input
44temp[2-4]_fault
