When that happens that would conflict with your firmware path and I don't expect your devices to accept the "invalid" signature of those files. So I would prefer if you follow Felipe's naming scheme and put these (this and the other remoteprocs) in: qcom/sm8350/microsoft/* Thanks, Bjorn > +}; > + > +&apps_rsc { > + pm8350-rpmh-regulators { > + compatible = "qcom,pm8350-rpmh-regulators";
