Hmm. I ran this using a recent version of dt-schema from github DT_DOC_CHECKER=~/Development/qualcomm/dt-schema/tools/dt-doc-validate DT_EXTRACT_EX=~/Development/qualcomm/dt-schema/tools/dt-extract-example DT_MK_SCHEMA=~/Development/qualcomm/dt-schema/tools/dt-mk-schema DT_CHECKER=~/Development/qualcomm/dt-schema/tools/dt-validate make DT_CHECKER_FLAGS=-m dt_binding_check O=$BUILDDIR DT_DOC_CHECKER=$DT_DOC_CHECKER DT_EXTRACT_EX=$DT_EXTRACT_EX DT_MK_SCHEMA=$DT_MK_SCHEMA DT_CHECKER=$DT_CHECKER DT_SCHEMA_FILES=display/msm/dsi-controller-main.yaml -j `nproc` Neither of these throw an warning in my compile log arch/arm/boot/dts/qcom-msm8974-lge-nexus5-hammerhead.dts:&dsi0 arch/arm/boot/dts/qcom-msm8974pro-samsung-klte.dts:&dsi0 thanks for spotting >> - compatible = "qcom,mdss-dsi-ctrl"; >> + compatible = "qcom,sc7180-dsi-ctrl", "qcom,mdss-dsi-ctrl"; > already dropped in v4
