At this point of time, we would have one or two fixes on top of this
version of patches for xHCI.
I can post those patches patches based on this series, so that you can
just pick up those. But they are
more of some BUG case handling and all.

Great!! so may be once you are ready you can post, and i can add the
exynos part to the dwc3 and test things at my end.

Cool.
