Hi Rob

I will fix the build and update the patch.
I have a question below until then though.

Mihail

For an ad3552r or ad3542r you can setup a default output range and a custom one (only one of these options is possible). The custom range is configured with this child and the default can be choose with the adi,output-range-microvolt property below

The adi,output-range-microvolt is described bellow for each chip. I couldn't find a way to put it here.
Do you have any suggestion?
