 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:
