Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt is not converted to yaml. Rob, Arnd, I am considering to pick this series up this friday given the scale of other platforms that are using the same property and since I see for example commit 0fe0fbc867115659bbd9a0ab107d1fe9bcc432e8 (MIPS) in next-20210616. Unfortunately [1] does'nt give me much precedence either in immediate recent history. Let me know if you think we should wait on this.
