This is what we do, the DT is not a 100% map of the actual system, and we have no inverter driver, so that flag is used to indicate "some electronics" that flip the polarity. We should document that better though. > So whilst it might superficially make sense to change it for > all cases, make sure we get someone familiar with the board to > sanity check them. Was just thinking of those that I can test :) Yours, Linus Walleij
