This is out of order.  The general rule is that patches should
merge in a sequence that supports "git bisect" ... but this patch
allows an unbuildable configuration.

Also ... if this is an "EHCI/OHCI block" then you should be
adding the OHCI support too...

No comments from me on those two.

Only two quick comments on that one:

 - Please stop using the obsolete idiom of having the probe() and
   remove() methods split in two needless parts.

 - Pending for 2.6.24-early merge is code switching EHCI debug
   files to use debugfs.  Please make this code stick the OMAP
   registers into that framework ... specifically, don't add a
   new file with some OMAP-specific registers, just add them to
   the standard file.  You may need to tweak the setup a bit
   to alow that, maybe addding a method to struct ehci_hcd.
