+Description
+-----------
+
+The AHT10/AHT20 is a Temperature and Humidity sensor
+
+The address of this i2c device may only be 0x38
+
+Special Features
+----------------
+
+AHT20 has additional CRC8 support which is sent as the last byte of the sensor
+values.
+
+Usage Notes
+-----------
+
+This driver does not probe for AHT10/ATH20 devices, as there is no reliable
+way to determine if an i2c chip is or isn't an AHT10/AHT20. The device has
+to be instantiated explicitly with the address 0x38. See
+Documentation/i2c/instantiating-devices.rst for details.
