As the node in question has to describe the address-cells and size-cells. As these are needed for its children to then also have address-cells, size-cells and reg values without raising more warnings. See https://patchwork.ozlabs.org/patch/1273784 If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure dt-schema is up to date: pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade Please check and re-submit.
