There's a dtc update in -next which adds these new checks. It's been there for over a month now. Unlike other dtc checks, these are generally actual errors, so they are not off by default (enabled with W=1,2). In reality, there's only about 50-100 warnings. The way dts includes are structured and because the dtc checks don't have the original source file lines, it just multiplies the warnings. Rob
