I imagine those are okay? This. I would assume that these were existing warnings, so new board does not add anything new. Different question if new board comes with the same warning for compatible in TXT (not DT schema). > Or are we assuming soc.dtsi > is warning free? Or do we need to distinguish both cases? Warning free, or at least not many warnings, should be implied, otherwise I don't think it is possible to spot new warnings. > > I would like to see a build target for the warning free platforms, so > we can easily run it and check for no warnings.
