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
