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
