+Description
+-----------
+
+This driver implements support for Texas Instruments TMP421, TMP422
+and TMP423 temperature sensor chips. These chips implement one local
+and up to one (TMP421), up to two (TMP422) 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
