+
+Description
+-----------
+
+The SHT10, SHT11, SHT15, SHT71, and SHT75 are humidity and temperature
+sensors.
+
+The devices communicate using two GPIO lines.
+
+Supported resolutions for the measurements are 14 bits for temperature and 12
+bits for humidity, or 12 bits for temperature and 8 bits for humidity.
+
+The humidity calibration coefficients are programmed into an OTP memory on the
+chip. These coefficients are used to internally calibrate the signals from the
+sensors. Disabling the reload of those coefficients allows saving 10ms for each
+measurement and decrease power consumption, while loosing on precision.
+
+Some options may be set directly in the sht15_platform_data structure
+or via sysfs attributes.
+
+Notes:
+  * The regulator supply name is set to "vcc".
+  * If a CRC validation fails, a soft reset command is sent, which resets
+    status register to its hardware default value, but the driver will try to
+    restore the previous device configuration.
+
+Platform data
+-------------
+
+* checksum:
+  set it to true to enable CRC validation of the readings (default to false).
+* no_otp_reload:
+  flag to indicate not to reload from OTP (default to false).
+* low_resolution:
+  flag to indicate the temp/humidity resolution to use (default to false).
+
+Sysfs interface
+---------------
+
+* temp1_input:     temperature input
+* humidity1_input: humidity input
+* heater_enable:   write 1 in this attribute to enable the on-chip heater,
+                   0 to disable it. Be careful not to enable the heater
+                   for too long.
+* temp1_fault:     if 1, this means that the voltage is low (below 2.47V) and
+                   measurement may be invalid.
+* humidity1_fault: same as temp1_fault.
