Hi, I saw this earlier, but didn't think it important to mention, but: On Fri, Sep 23, 2016 at 2:41 PM, H.

Ofcourse, this is under control of the DT-maintainer(s) of the device (if I'm not mistaking), but throwing an error on DT parse if (one of) these condition(s) is met yields better info to the DT-maintainer than a /0 error... If you (or others) agree, could you add this to the patch?
