I have only this one particular flavor so I would prefer to upstream only this one. I do not know all the possible combinations or for example the most interesting ones. I think after this patchset we can refactor the DTS whenever its needed - split common parts, add new files. > I would prefer to at least apply the naming changes before merging.
