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>

The industrial I/O subsystem provides a unified framework for

drivers for many different types of embedded sensors using a

number of different physical interfaces (i2c, spi, etc).

A simple fifo based on kfifo. Note that this currently provides

no buffer events so it is up to userspace to work out how

often to read from the buffer.

Provides IIO core support for triggers. Currently these

This value controls the maximum number of consumers that a
