Hi Dirk, >>From my point of view the most promising avenue at this time is work that Geert has been doing to explore making things more flexible by updating the DT automatically at run time. He can expand on this but the idea is to add per-soc compat strings and otherwise update the DT into a per-SoC version. This ought to allow significant portions of the DT to be common between SoCs in the same R-Car generation for at lest Gen 2 and Gen 3.
