Each compatible has a different set of clocks which are associated with it.
Add in the list of clocks for each compatible.

minItems are 6, so does it actually work?

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
