+Kernel driver tids
+===================
+
+Supported Chips:
+
+  * WSEN TIDS
+
+    Prefix: 'tids'
+
+    Addresses scanned: None
+
+    Datasheet:
+
+      English: https://www.we-online.com/components/products/manual/Manual-um-wsen-tids-2521020222501%20(rev1.2).pdf
+
+Author: Thomas Marangoni <Thomas.Marangoni@...om-group.com>
+
+
+Description
+-----------
+
+This driver implements support for the WSEN TIDS chip, a temperature
+sensor. Temperature is measured in degree celsius. In sysfs interface,
+all values are scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
+
+Usage Notes
+-----------
+
+The device communicates with the I2C protocol. Sensors can have the I2C
+address 0x38 or 0x3F. See Documentation/i2c/instantiating-devices.rst for methods
+to instantiate the device.
+
+Sysfs entries
+-------------
+
+=============== ============================================
+temp1_input     Measured temperature in millidegrees Celsius
+update_interval The interval for polling the sensor, in
+                milliseconds. Writable. Must be 5, 10, 20
+                or 40.
+temp1_max_hyst  The temperature in millidegrees Celsius, that
+                is triggering the temp1_max_alarm. Writable.
+                The lowest possible value is -39680 and the
+                highest possible value is 122880. Values are
+                saved in steps of 640.
+temp1_min_hyst  The temperature in millidegrees Celsius, that
+                is triggering the temp1_min_alarm. Writable.
+                The lowest possible value is -39680 and the
+                highest possible value is 122880. Values are
+                saved in steps of 640.
+temp1_max_alarm The alarm will be triggered when the level
+                reaches the value specified in
+                temp1_max_hyst. It will reset automatically
+                once it has been read.
+temp1_min_alarm The alarm will be triggered when the level
+                reaches the value specified in
+                temp1_min_hyst. It will reset automatically
+                once it has been read.
