I'm not interested in what the SDK binding says, or what the SDK kernel does. I'm interested in whether there's a U-Boot compatibility issue, as was previously alleged. If there isn't, then there's no need for fsl,dpaa *or* fsl,dpa-ethernet. -Scott -- 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
