Thanks JMCC, I have overlooked the sources listed above. But still I have not found a repository for the package media-buster-legacy-tinkerboard itself.

Great work, thanks a lot. After a long time I have upgraded to buster, For curiosity, if you can be bothered, I would like to understand what the packages actually do? Is there a repository to find out about it? I guess there are several packages (kernel and media-buster-legacy-tinkerboard) involved?
