Instead have boolean properties for all states. line_b { gpio-hog; gpios = <6 0>; output-low; line-name = "foo-bar-gpio"; } Then use of_property_read_bool() in the code to check which state is to be selected intially. You can check that no mutually exclusive state are selected, I don't like that an arbitrary string select the state like that, if we do it that way an enumerator would be better, I prefer bools.
