Kernel driver htu21

===================



Supported chips:

  * Measurement Specialties HTU21D

    Prefix: 'htu21'

    Addresses scanned: none

    Datasheet: Publicly available at the Measurement Specialties website

    http://www.meas-spec.com/downloads/HTU21D.pdf





Author:

  William Markezana <william.markezana@meas-spec.com>



Description

-----------



The HTU21D is a humidity and temperature sensor in a DFN package of

only 3 x 3 mm footprint and 0.9 mm height.



The devices communicate with the I2C protocol. All sensors are set to the

same I2C address 0x40, so an entry with I2C_BOARD_INFO("htu21", 0x40) can

be used in the board setup code.



This driver does not auto-detect devices. You will have to instantiate the

devices explicitly. Please see Documentation/i2c/instantiating-devices

for details.



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 11 ms for

humidity and 44 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. For

this reason, the driver performs no more than two measurements per second and

reports cached information if polled more frequently.



Different resolutions, the on-chip heater, using the CRC checksum and reading

the serial number are not supported yet.

Kernel driver ltc3815

=====================



Supported chips:

  * Linear Technology LTC3815

    Prefix: 'ltc3815'

    Addresses scanned: -

    Datasheet: http://www.linear.com/product/ltc3815



Author: Guenter Roeck <linux@roeck-us.net>





Description

-----------



LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter.





Usage Notes

-----------



This driver does not probe for PMBus devices. You will have to instantiate

devices explicitly.



Example: the following commands will load the driver for an LTC3815

at address 0x20 on I2C bus #1:



# modprobe ltc3815

# echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
