For now I think > this is pretty much all that is proximity specific. I did a Documentation/devicetree/bindings/iio/common.yaml: https://source.puri.sm/guido.gunther/linux-imx8/commit/8b91f0b7fa76ca4b2f3cdc251411829f71f8d810 so we can add new properties there and move iio-bindings.txt over. Does that work as well? If so I'll send out a v4.
