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
