Both features are not "necessary" for any driver, but that doesn't mean we work around it by throwing a platform driver at it. We already have this same problem with PL010 UARTs, and the DT support for AMBA has the ability to specify the AMBA ID. Moreover, there is nothing which prevents you from declaring an AMBA device with an appropriate AMBA ID for the driver to bind to - which is presumably something very similar to what you're already doing with a platform device. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
