I resend it for now because i think v2 patch looks more clearly than the old one, the v1 patch could just be superseded. -- 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
