I think it's just that with commit d8e5f0eca1e8 we now have phy enabled
earlier and calling musb_host_setup() with phy enabled sends it into
a loop of trying to force the host mode with nothing connected. This
loops seems to end after few seconds if there are devices connected,
but keeps going if there's nothing connected.
Regards,
Tony
