What driver is normally used for versatile express pata? This driver is kind of legacy in that it was created when there was a split between platform_device and of_platform_devices. But that split was a bad idea and the same driver should be used regardless of whether or not DT is enabled. pata_of_platform.c really should be removed. So, instead of removing the PPC_OF restriction from pata_of_platform.c, you should look at adding DT support to the existing binding. Bonus points if you can roll pata_of_platform.c support into pata_platform.c (assuming that is the correct driver). g. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
