Finally, here is the implementation Hans and I agreed on. Plus, all potential users I could spot already converted. Renesas R-Car driver was added on top. This series was tested on a Renesas Lager board (R-Car H2). I had to hack some error cases into the code to verify the workings. I couldn't create an error case otherwise, this is why further testing with more complex setups is very welcome. For my taste, there is still too much boilerplate code for drivers left. Plus, it is also too easy to put it too early or too late. But I haven't come up with a better idea yet. And it is time to get this somehow forward.
