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.

Kernel driver sht21
===================
Supported chips:
* Sensirion SHT21
Prefix: 'sht21'
Addresses scanned: none
Datasheet: Publicly available at the Sensirion website
http://www.sensirion.com/en/pdf/product_information/Datasheet-humidity-sensor-SHT21.pdf
* Sensirion SHT25
Prefix: 'sht21'
Addresses scanned: none
Datasheet: Publicly available at the Sensirion website
http://www.sensirion.com/en/pdf/product_information/Datasheet-humidity-sensor-SHT25.pdf
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.
