Description
|
|
-----------
|
|
|
|
This driver implements support for Texas Instruments TMP421, TMP422,
|
|
TMP423, TMP441, and TMP442 temperature sensor chips. These chips
|
|
implement one local and up to one (TMP421, TMP441), up to two (TMP422,
|
|
TMP442) 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**
