Basically yes. The point that Chen-Yu made is that he and other developers don't have all boards available to verify that all of these boards use the same layout for their wiring. Therefore they just leave these bits out. I'm actually working on a small patch to add these regulator bits to the BananaPi and possibly BananaPro dts files. I will post it soon, when I gathered enough information to ensure everything works fine. But anyway, we're getting offtopic here. So let's postpone this discussion until then. Cheers, Timo
