Our focus is on the SDP500. SDP510 is the same software-wise so I just mention it but I agree that I should add it as compatible in the code. > > + > > +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. This sounds like a more serious comment. We will definitely continue using this driver internally for now. But do you think it's still worth adding it as a separate driver instead of leaving it for "trivial-devices"? It has been a useful driver for us so we thought it is worth sharing. > > Cheers, > Conor. > > > + > > +examples: > > + - | > > + i2c { > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pressure@40 { > > + compatible = "sensirion,sdp500"; > > + reg = <0x40>; > > + vdd-supply = <&foo>; > > + }; > > + }; > > -- > > 2.30.2
