I did only have a quick look though, so please correct me if that is not the case. If they are compatible, please set this up to use a fallback compatible - for example allow compatible = "ti,hdc3020"; compatible = "ti,hdc3021", "ti,hdc3020"; compatible = "ti,hdc3022", "ti,hdc3020"; > + > + interrupts: > + maxItems: 1 > + > + reg: > + maxItems: 1 > + > +required: > + - compatible > + - reg > + > +additionalProperties: false > + > +examples: > + - | > + i2c { > + #address-cells = <1>; > + #size-cells = <0>; > + > + humidity@47 { The generic node name here should probably be "humidity-sensor".
