I was asked about this patch series, and see that you last posted it in December. I think you should rebase it to linux-5.7-rc6 and post the entire series again to make progress, as it's unlikely that any maintainer would pick up the patches from last year. For the contents, everything seems reasonable to me, but I noticed that you are adding a property to the /chosen node without adding the corresponding documentation to Documentation/devicetree/bindings/chosen.txt Please add that, and Cc the devicetree maintainers on the updated patch.
