Hierarchy: Hamoa ComE Carrier Board -> SoM -> SiP(This SiP hardware is effectively the same as the SoM on the Hamoa EVK) -> SoC Hamoa evk Carrier Board -> SoM -> SoC So I think I write a wrong dt binding about Hamoa ComE: correct here: I think the binding should be: 1. - items: - enum: - qcom,hamoa-iot-come - const: qcom,hamoa-iot-come-som - const: qcom,hamoa-iot-come-sip - const: qcom,x1e80100 or 2. - items: - enum: - qcom,hamoa-iot-come - const: qcom,hamoa-iot-come-som - const: qcom,hamoa-iot-som - const: qcom,x1e80100 > > related components. > > > > Hierarchy: > > > > Carrier Board > > -> SoM > > -> SiP > > -> SoC > > Drop.

This ComE SiP hardware is effectively the same as the SoM on the Hamoa EVK, It's just called differently on a different board. I should update my commit msg show this. > Best regards, > Krzysztof > Thanks, Yuanjie
