The fact is that OMAP can't handle port handoff (go figure) and if we use those functions, we might end up in a situation where USB doesn't work just because you connected a full speed device. By not using those functions, we guarantee that the full speed device won't get enumerated but USB will still be functional after you disconnect such device. We could add a bunch of __maybe_unused annotation to all those ehci_* functions. What do you say Alan ? -- balbi
