I'm not saying that it has to match the physical device fitted - I'm merely suggesting not using nxp,tda1998x which could (and as Sebastian has found, does) conflict with other devices with different properties. We still auto-detect the exact device type by reading the ID register because that's the most reliable way to detect exactly what kind of device is fitted to the board. -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. -- 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
