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

* Analog Devices AD5272 digital potentiometer



The node for this device must be a child node of a I2C controller, hence

all mandatory properties for your controller must be specified. See directory:



        Documentation/devicetree/bindings/i2c



for more details.



Required properties:

	- compatible:  	Must be one of the following, depending on the model:

			adi,ad5272-020

			adi,ad5272-050

			adi,ad5272-100

			adi,ad5274-020

			adi,ad5274-100



Optional properties:

 - reset-gpios: GPIO specification for the RESET input. This is an

		active low signal to the AD5272.



Example:

ad5272: potentiometer@2f {

	reg = <0x2F>;

	compatible = "adi,ad5272-020";

	reset-gpios = <&gpio3 6 GPIO_ACTIVE_HIGH>;
