Removing it is not strictly necessary for the series to function, I will re-upload the series and omit the following changes: - [PATCH v6 8/9] dts: mtk-mdp: remove mediatek,vpu property from primary MDP device - [PATCH v6 9/9] dt-bindings: mediatek: remove vpu requirement from mtk-mdp Do please let me know if you meant something different.
