If you can check it in the driver, you can also decide to ignore it if it were offset by 0x04 (possibly printing a warning.) That opens up the ability to fix the older Tegra DT files going forward while still remaining compatible with existing DT files, and avoiding the need for a complex note about this. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- 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
