[PATCH v2 0/7] iio: mlx90614 enhancements

["Vianney le Clément de Saint-Marcq" <vianney.leclement-buIOx9BAs4sybS5Ee8rs3A@public.gmane.org>]

This series follows up on the first series sent on February 25.  I have dropped
the filter configuration for now, as I am still trying to figure out how to do
that properly.

This set of patches adds the following additional features to the
mlx90614 temperature sensor driver.

* Support for the dual IR sensor model (patch 3)
* Emissivity setting (patches 4 and 5)
* Power management (patch 6)
* Handle errors in temperature reading (patch 7)

The changes have been split into 7 patches to ease code review.
Patches 1 and 2 contain mandatory symbol definitions, which have already
been applied to the togreg branch of iio.git.
Patches 3, 5-7 implement the additional features and are mostly independent
from each other.
Patch 4 introduces IIO_CHAN_INFO_EMISSIVITY in iio core and is a prerequisite
of patch 5.

Patch 6 introduces device tree bindings and is the only one sent to the
devicetree list.

Patch set history:
v2: * Drop processed temperature output (v1 patch 3)
    * Drop raw IR values for now (v1 patch 7)
    * Drop iir, fir, and gain attributes for now (v1 patch 5)
    * Introduce standard attribute for emissivity (patches 4 and 5)
    * Add patch 7, fixing wrong readings
    * Return -EINTR when wake-up is interrupted during read (patch 6)
    * Make adding vendor prefix explicit in commit message of patch 6
