Ok.

I guess we need to create a proximity specific binding file.

Documentation/devicetree/bindings/iio/proximity.yaml

Guido, could you do a v4 adding such a file. For now I think
this is pretty much all that is proximity specific.

At somepoint we should convert the subsystem wide iio-bindings.txt
but not today!

Thanks,
