If they have no meaning, they should go. They're unnecessary and make things more confusing. I'd expect the example to be: beeper: beeper { compatible = "gpio-beeper"; gpios - <&gpio3 23 0>; }; And if we have multiple beepers, something like: beeper0: beeper0 { ... }; beeper1: beeper1 { ... }; Thanks, Mark. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
