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

  sensor and MLX90632 is most suitable for consumer applications where

  measured object temperature is in range between -20 to 200 degrees

  Celsius with relative error of measurement below 1 degree Celsius in

  object temperature range for industrial applications. Since it can

  operate and measure ambient temperature in range of -20 to 85 degrees

  Celsius it is suitable also for outdoor use.



  Be aware that electronics surrounding the sensor can increase ambient

  temperature. MLX90632 can be calibrated to reduce the housing effect via

  already existing EEPROM parameters.



  Since measured object emissivity effects Infra Red energy emitted,

  emissivity should be set before requesting the object temperature.

There are various applications for the Infra Red contactless temperature sensor

and MLX90632 is most suitable for consumer applications where measured object

temperature is in range between -20 to 200 degrees Celsius with relative error

of measurement below 1 degree Celsius in object temperature range for

industrial applications. Since it can operate and measure ambient temperature

in range of -20 to 85 degrees Celsius it is suitable also for outdoor use.

temperature. MLX90632 can be calibrated to reduce the housing effect via

already existing EEPROM parameters.



Since measured object emissivity effects Infra Red energy emitted, emissivity

should be set before requesting the object temperature.



Required properties:

  - compatible: should be "melexis,mlx90632"

  - reg: the I2C address of the sensor (default 0x3a)



Example:



mlx90632@3a {

	compatible = "melexis,mlx90632";

	reg = <0x3a>;

};
