| Description | |
| ----------- | |
| This driver implements support for Texas Instruments TMP401, TMP411, | |
| TMP431, TMP432, TMP435, and TMP461 chips. These chips implement one or two | |
| remote and one local temperature sensors. Temperature is measured in degrees | |
| Celsius. Resolution of the remote sensor is 0.0625 degree. Local | |
| sensor resolution can be set to 0.5, 0.25, 0.125 or 0.0625 degree (not | |
| supported by the driver so far, so using the default resolution of 0.5 | |
| degree). | |
| The driver provides the common sysfs-interface for temperatures (see | |
| Documentation/hwmon/sysfs-interface under Temperatures). | |
| The TMP411 and TMP431 chips are compatible with TMP401. TMP411 provides | |
| some additional features. | |
| * Minimum and Maximum temperature measured since power-on, chip-reset | |
| Exported via sysfs attributes tempX_lowest and tempX_highest. | |
| * Reset of historical minimum/maximum temperature measurements | |
| Exported via sysfs attribute temp_reset_history. Writing 1 to this | |
| file triggers a reset. | |
| TMP432 is compatible with TMP401 and TMP431. It supports two external | |
| temperature sensors. | |
| TMP461 is compatible with TMP401. It supports offset correction | |
| that is applied to the remote sensor. | |
| * Sensor offset values are temperature values | |
| Exported via sysfs attribute tempX_offset |
