    Then you should have known that all [EO]HCI controllers use MMIO, and it's 
pointless to call them "MMIO [EO]HCI controller" in your title and in your 
"compatible" prop. Because you plainly create an impression that there's some 
other kind of [EO]HCI controllers out there, e.g. I/O mapped (for which a 
separate binding would be needed?).

    Yes, I meant Alan by [EO]HCI expert. He's not DT expert, unfortunately, AFAIK.

    Well, if nothing else helps... :-(

    I didn't hear your reply to my last mail which laid out some plan of 
dealing with ehci-ppc-of.c. Your "technical" argument against using "usb-ehci" 
didn't really make much sense to me and I told you why and what to do to get 
things right. You chose to not even reply to this and instead post "100% 
fready for merge" patchset.
    Sigh, it's a pity Alistair Popple's patches [1], [2] didn't get merged. He 
simply disappeared somewhere.

    Do you think calling other people's opinions "pure bike-shedding" helps 
the discussion?

    The worst thing is once the bindings get merged, they're "set in stone" 
and it won't be easy to fix, if at all possible... :-(
