The binding only describes the CS7542, which is the only part I can test, so in v2 the description says just that, and that the other CS75xx parts and the Cortina Access ones (the same block, see the discussion on patch 7) are to be added with their own compatible and "cortina,cs7542-uart" as the fallback. The compatible stays a single const until one of them is added. Thanks, Fil
