Description
-----------

This driver implements support for the Sensirion SHT4x chip, a humidity
and temperature sensor. Temperature is measured in degree celsius, relative
humidity is expressed as a percentage. 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 0x44. See Documentation/i2c/instantiating-devices.rst for methods
to instantiate the device.

Sysfs entries

=============== ============================================
temp1_input     Measured temperature in millidegrees Celsius
humidity1_input Measured humidity in %H
update_interval The minimum interval for polling the sensor,
                in milliseconds. Writable. Must be at least
                2000.
