2013-08-17iio: Add tmp006 IR temperature sensorPeter Meerwald3-0/+312
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 Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Cc: Grygorii Strashko <grygorii.strashko@ti.com> Cc: Lars-Peter Clausen <lars@metafoo.de> Cc: Jonathan Cameron <jic23@kernel.org> Cc: LM Sensors <lm-sensors@lm-sensors.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
