Hi Rob,

Thank you for running the dt_binding_check on this patch!

This error occurred because in v4, while I updated the dts compatible property 
definition to "bst,c1200-sdhci" (as requested in review), I failed to update 
the compatible string in the example node accordingly. The example was still 
using the old "bst,c1200-dwcmshc-sdhci", causing the schema validation to fail.

I have now corrected the example's compatible string from:
    compatible = "bst,c1200-dwcmshc-sdhci";
to:
    compatible = "bst,c1200-sdhci";

Following your suggestion, I've upgraded dtschema:
    pip3 install dtschema --upgrade

and verified the fix with:
    make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/mmc/bst,c1200-sdhci.yaml

The binding now passes all validation checks. This fix will be included in v5.

Best regards,
Albert Yang
