| 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 |
