You've sent a variantion on this email twice today. The usual process for sending support upstream is via a git commit with appropriate pieces. I suggest having a look at the means of git commit/format-patch/send-email. Other than just a config file, you'll also need to add the upstream (from Linux) dts file. The OrangePi Zero2 commit [1] would be a good example to base you patch on.
