Looking at the series, I don't think this necessarily needs to go
through the Tegra tree. Given that you have backwards-compatibility with
older device trees, applying this separately to the USB tree should work
fine. Once the soc/tegra and DT bits and the USB bits get combined they
should enable the new functionality, but nothing should break if things
are applied separately.

If so, I can just pick up the rest and let Felipe or Greg pick this one
up.

Dmitry, can you confirm that this patch should be applicable separately?
If so:
