Merge tag 'staging-4.17-rc1' of git://git.kernel.org/pub/scm/linux/ke…

…rnel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here is the big set of Staging/IIO driver patches for 4.17-rc1.

  It is a lot, over 500 changes, but not huge by previous kernel release
  standards. We deleted more lines than we added again (27k added vs.
  91k remvoed), thanks to finally being able to delete the IRDA drivers
  and networking code.

  We also deleted the ccree crypto driver, but that's coming back in
  through the crypto tree to you, in a much cleaned-up form.

  Added this round is at lot of "mt7621" device support, which is for an
  embedded device that Neil Brown cares about, and of course a handful
  of new IIO drivers as well.

  And finally, the fsl-mc core code moved out of the staging tree to the
  "real" part of the kernel, which is nice to see happen as well.

  Full details are in the shortlog, which has all of the tiny cleanup
  patches described.

  All of these have been in linux-next for a while with no reported
  issues"

+Link to datasheet: https://www.melexis.com/en/documents/documentation/datasheets/datasheet-mlx90632
+
+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.
+
+Required properties:
+  - compatible: should be "melexis,mlx90632"
+  - reg: the I2C address of the sensor (default 0x3a)
