dt-bindings:iio:temperature:melexis,mlx90632 conversion to yaml
Technically this could have gone in trivial-devices.yaml, but I have
kept it as a separate binding due to the detailed additional description
from the text file.

There are various applications for the Infra Red contactless temperature
16
+
sensor and MLX90632 is most suitable for consumer applications where
17
+
measured object temperature is in range between -20 to 200 degrees
18
+
Celsius with relative error of measurement below 1 degree Celsius in
19
+
object temperature range for industrial applications. Since it can
20
+
operate and measure ambient temperature in range of -20 to 85 degrees
21
+
Celsius it is suitable also for outdoor use.
22
+
23
+
Be aware that electronics surrounding the sensor can increase ambient
24
+
temperature. MLX90632 can be calibrated to reduce the housing effect via
25
+
already existing EEPROM parameters.
26
+
27
+
Since measured object emissivity effects Infra Red energy emitted,
28
+
emissivity should be set before requesting the object temperature.
