The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.

Sorry, picked the wrong link. Put all pinctrl patches together into this series to make it easier to follow (but v2 because v1 was for changing only mmc pinctrl and to have no conflicts or "broken" commits): https://patchwork.kernel.org/project/linux-mediatek/list/?series=692462 >Yours, >Linus Walleij regards Frank
