I see no mention of the sdp510 elsewhere in this patch though.. If you're trying to add support for both, then add a compatible for the sdp510 that falls back to the sdp500. > + > +properties: > + compatible: > + const: sensirion,sdp500 > + > + reg: > + maxItems: 1 > + > +required: > + - compatible > + - reg > + > +additionalProperties: false Other than the fact that a fallback compatible might be required here, this looks like a candidate for trivial-devices.yaml.
