As replied to the other one I can't figure out a syntax that allows me to do that. Get an issues along the lines of ... iio/dac/ti,dac082s085.yaml: allOf:0: 'not' is not one of ['$ref', 'if', 'then', 'else'] (obviously that's form the other driver that does this).

Hi Rob, I still have an open question below on this one. If you have a chance to take a look that would be great.
