+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.rst 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
