A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

That's an ABI change from what was > already supported. Hi Rob, I thought for supplies the convention was that if the power is needed for functioning device then to put them as required. In case were they were missing in an original binding allow stub regulators to deal with a DT that predates that. Non linux cases are obviously trickier to predict but these supplies must be on or the binding wouldn't have worked before this point. I remember I was very much on the side that they were optional and convinced by others that this was the way to go. We've added supplies for old bindings as required in the past so probably broken someone if I have this wrong :( Jonathan
