I'm fairly certain we can just drop the OF_DEV_AUXDATA entry here. I haven't been following this as closely as I should, but I know that the comment for this table says that the whole purpose is to override device names and that it should be temporary. We don't need to do any overriding of device names here, do we? When I drop this (and the ohci and phy) entries from my table I can still boot and still can use USB. The big difference is what shows up in dmesg [ 1.605000] s5p-ehci s5p-ehci: S5P EHCI Host Controller Becomes: [ 1.550000] s5p-ehci 12110000.usb: S5P EHCI Host Controller ...and some sysfs paths change. -Doug
