+Kernel driver ds620
+===================
+
+Supported chips:
+ * Dallas Semiconductor DS620
+ Prefix: 'ds620'
+ Datasheet: Publicly available at the Dallas Semiconductor website
+ http://www.dalsemi.com/
+
+Authors:
+ Roland Stigge <stigge@antcom.de>
+ based on ds1621.c by
+ Christian W. Zuckschwerdt <zany@triq.net>
+
+Description
+-----------
+
+The DS620 is a (one instance) digital thermometer and thermostat. It has both
+high and low temperature limits which can be user defined (i.e. programmed
+into non-volatile on-chip registers). Temperature range is -55 degree Celsius
+to +125. Between 0 and 70 degree Celsius, accuracy is 0.5 Kelvin. The value
+returned via sysfs displays post decimal positions.
+
+The thermostat function works as follows: When configured via platform_data
+(struct ds620_platform_data) .pomode == 0 (default), the thermostat output pin
+PO is always low. If .pomode == 1, the thermostat is in PO_LOW mode. I.e., the
+output pin PO becomes active when the temperature falls below temp1_min and
+stays active until the temperature goes above temp1_max.
+
+Likewise, with .pomode == 2, the thermostat is in PO_HIGH mode. I.e., the PO
+output pin becomes active when the temperature goes above temp1_max and stays
+active until the temperature falls below temp1_min.
+
+The PO output pin of the DS620 operates active-low.

+Author:
+ Urs Fleisch <urs.fleisch@sensirion.com>
+
+Description
+-----------
+
+The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of
+only 3 x 3 mm footprint and 1.1 mm height. The difference between the two
+devices is the higher level of precision of the SHT25 (1.8% relative humidity,
+0.2 degree Celsius) compared with the SHT21 (2.0% relative humidity,
+0.3 degree Celsius).
+
+The devices communicate with the I2C protocol. All sensors are set to the same
+I2C address 0x40, so an entry with I2C_BOARD_INFO("sht21", 0x40) can be used
+in the board setup code.
+
+sysfs-Interface
+---------------
+
+temp1_input - temperature input
+humidity1_input - humidity input
+
+Notes
+-----
+
+The driver uses the default resolution settings of 12 bit for humidity and 14
+bit for temperature, which results in typical measurement times of 22 ms for
+humidity and 66 ms for temperature. To keep self heating below 0.1 degree
+Celsius, the device should not be active for more than 10% of the time,
+e.g. maximum two measurements per second at the given resolution.
+
+Different resolutions, the on-chip heater, using the CRC checksum and reading
+the serial number are not supported yet.
