+Description
+-----------
+
+This driver implements support for the Sensirion SHTC1, SHTW1, and SHTC3
+chips, a humidity and temperature sensor. Temperature is measured in degrees
+celsius, relative humidity is expressed as a percentage.
+
+The device communicates with the I2C protocol. All sensors are set to I2C
+address 0x70. See Documentation/i2c/instantiating-devices.rst for methods to
+instantiate the device.
+
+There are two options configurable by means of shtc1_platform_data:
+
+1. blocking (pull the I2C clock line down while performing the measurement) or
+   non-blocking mode. Blocking mode will guarantee the fastest result but
+   the I2C bus will be busy during that time. By default, non-blocking mode
+   is used. Make sure clock-stretching works properly on your device if you
+   want to use blocking mode.
+2. high or low accuracy. High accuracy is used by default and using it is
+   strongly recommended.
