22Description
23-----------
24
25The AHT10 is a Temperature and Humidity sensor
26
27The address of this i2c device may only be 0x38
28
29Usage Notes
30-----------
31
32This driver does not probe for AHT10 devices, as there is no reliable
33way to determine if an i2c chip is or isn't an AHT10. The device has
34to be instantiated explicitly with the address 0x38. See
35Documentation/i2c/instantiating-devices.rst for details.
