Well, it could also be that the clock is wired to some other clock which is always on (which I guess is why the driver allows this in the first place, there's a lot of sloppy code around stuff like that in the tree). > If the point of schema is to find errors in DTs, doesn't it make more sense > to fix the DTs than to weaken the schema just to shut it up? I do agree on this point though, given that the clock is actually required for useful operation what's happening here is that the schema is detecting an error in the use of the binding.
