SHT85 is a temperature and humidity sensor with the same interface
as SHT3x.

Changes since v1:
* sht3x.c - dropped all changes, added {"sht85", sht3x} to i2c_device_id[]
* Kconfig - added information about SHT85 support
* Documentation: changed "Datasheets" -> "Datasheet"
* Documentation: added information about SHT85 address == 0x44

 series of humidity and temperature sensors. Temperature is measured in degrees
 celsius, relative humidity is expressed as a percentage. In the sysfs interface,
 all values are scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
 
-The device communicates with the I2C protocol. Sensors can have the I2C
-addresses 0x44 or 0x45 (0x4a or 0x4b for sts3x), depending on the wiring. See
-Documentation/i2c/instantiating-devices.rst for methods to instantiate the
-device.
+The device communicates with the I2C protocol. SHT3x sensors can have the I2C
+addresses 0x44 or 0x45 (0x4a or 0x4b for sts3x), depending on the wiring. SHT85
+address is 0x44 and is fixed. See Documentation/i2c/instantiating-devices.rst for
+methods to instantiate the device.
 
 Even if sht3x sensor supports clock-stretch (blocking mode) and non-stretch
 (non-blocking mode) in single-shot mode, this driver only supports the latter.
