I think the right solution here is to drop any specified default in the common properties binding and replace with something like, "If a binding supports these properties, then that binding should also specify the default if none of these properties are present. In such cases, little-endian is the preferred default, but it is not a requirement" g. -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
