With [1], the DM support for the EHCI controller was added.  There is
still some work to be done to make it better, because there are still
some #defines that need to assign the reset GPIO's. Ideally we'd get
rid of the GPIO defines and use the device tree to address the reset.
It isn't perfect, but it's better than having no USB at all.  The
am3517_evm and omap3_logic_somlv have them working. Make sure the
board files have the legacy USB stuff removed [2]

Let me know if there is anything I can do to help.
