-Description
------------
-
-Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically,
-this is kernel hwmon driver for ABx500.
-
-There are some GPADCs inside ABx500 which are designed for connecting to
-thermal sensors, and there is also a thermal sensor inside ABx500 too, which
-raises interrupt when critical temperature reached.
-
-This abx500 is a common layer which can monitor all of the sensors, every
-specific abx500 chip has its special configurations in its own file, e.g. some
-sensors can be configured invisible if they are not available on that chip, and
-the corresponding gpadc_addr should be set to 0, thus this sensor won't be
-polled.

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