fsl-usb.txt uses "dr_mode" here, which might make sense to reuse given some of
the shared IP in question for device mode:

 - dr_mode : indicates the working mode for "fsl-usb2-dr" compatible
  controllers.  Can be "host", "peripheral", or "otg".  Default to
  "host" if not defined for backward compatibility.

What does 'dr' mean?

After some searching, it looks like it means "dual-role", which seems
appropriate terminology for the tegra SoC as well.

Thanks for looking that up.

Well maybe, but it could mean data reverse mode or distinctive
ring...I like Stephen's nice device-tree-friendly naming and
explanation :-) Are we stuck with this?

Regards,
Simon
