I hope Rob or somebody more knowledgeable on this can > clarify the usage. If you know how many (or a range) entries there are for gpio-ranges, then maxItems is good. If you don't, then 'gpio-ranges: true' is fine. That doesn't make the property a boolean, but just says the property can be present. Rob
