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?
I think there's value in staying common with similar bindings on other platforms, yes. Sorry. :)
Ack from me too. If there's an existing convention, I'd prefer to stick with it. Sorry, I should have looked this up before coming up with something new.
