In HDMI case, which one is better DT ? port@0 { type = "video"; endpoint { remote-endpoint = <&xxx>; }; }; port@1 { type = "sound"; endpoint { remote-endpoint = <&xxx>; }; }; or port { endpoint { type = "video"; remote-endpoint = <&xxx>; }; endpoint { type = "sound"; remote-endpoint = <&xxx>; }; }; If 2nd one is better, type on endpoint is needed. -- 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
