txt bindings are somewhat deprecated now, this specific binding was already converted to the new json-schema, although didn't land yet, you should base your changes on that, you can pick the following patch: https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20200306085513.76024-1-ikjn@chromium.org/ Also, the kernel test robot, reported a build problem, so fix the problems on the second version. Thanks, Enric
