The rule is that we don't intentionally break things, so please post a
patch that keeps the existing platform driver there. Ideally we get a DT-only
clps711x for the merge window as well, and if that happens we can add another
patch on top to remove that syscon-pdev support again but then we will
have a bisectable kernel that works for every point inbetween.
