Nuno Sá f110f3188e iio: temperature: Add support for LTC2983
The LTC2983 is a Multi-Sensor High Accuracy Digital Temperature
Measurement System. It measures a wide variety of temperature sensors and
digitally outputs the result, in °C or °F, with 0.1°C accuracy and
0.001°C resolution. It can measure the temperature of all standard
thermocouples (type B,E,J,K,N,S,R,T), standard 2-,3-,4-wire RTDs,
thermistors and diodes.

Song Hongyan 59d0f2da35 iio: hid: Add temperature sensor support
Environmental temperature sensor is a hid defined sensor,
it measures temperature.

More information can be found in:
http://www.usb.org/developers/hidpage/HUTRR39b.pdf

According to IIO ABI definition, IIO_TEMP data output unit is
milli degrees Celsius. Add the unit convert from degree to milli degree.

Manivannan Sadhasivam 948b707df8 iio:temperature: Add support for TI TMP007 sensor
This patch adds support for TI TMP007 - 16 bit IR thermopile sensor with integrated Math engine.
Sensor takes care of calculating the object temperature with the help of calibrated constants stored in non-volatile memory,
thereby reducing the calculation overhead.

Peter Meerwald e5a6394218 iio: Add tmp006 IR temperature sensor
the TI TMP006 is a non-contact temperature sensor with I2C interface;
it measures the surface temperature of a distance object using a
thermopile to absorb IR energy emitted from the object

the sensor has two channels: IR sensor voltage (16-bit) and reference
temperature of the chip (14-bit); datasheet is here:
http://www.ti.com/lit/ds/symlink/tmp006.pdf

v2 (thanks to Grygorii Strashko, Lars-Peter Clausen, Jonathan Cameron
for review comments):
* power down device on driver remove
* use sign_extend32()
* style cleanup
* add comments what channel raw LSBs mean
* spelling of thermopile
