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.

But Why? Do you expect different clocks for others? If so, where are they? Anyway, drop useless "Phandle, clock specifier of". Clocks cannot be anything else than phandle and a clock specifier. Instead of using some cryptic ACRONYM_OR_SOME_CLK, describe them. Just like we do for other bindings.

Why do you need any dependency here in this binding? Best regards, Krzysztof

It's similar to process in Linux. Here QDSP6 processor runs each wifi radio functionality on a separate process. One process can't access other process resources, so this is termed as PD i.e protection domain. Here we have two pd's called root and user pd. We can correlate Root pd as root and user pd as user in linux. Root pd has more privileges than user pd. From remoteproc driver perspective, root pd corresponds to QDSP6 processor bring up and user pd corresponds to Wifi radio (WCSS) bring up. >> + >> +properties: >> + compatible: >> + enum: >> + - qcom,ipq5018-q6-mpd >> + - qcom,ipq9574-q6-mpd >> + >> + '#address-cells': true >> + >> + '#size-cells': true > > Why do you need both? > > If really needed, these should be const. > It's not required.
