On the other hand it does mean that the user can directly read the values - there's nothing that obviously tells the user that the binding is using datasheet register values rather than the actual driver strength numbers and given that software is supposed to provide an abstraction to make things easier it seems reasonably natural to assume the latter. -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
