No DTS part has been inclueded in this series, instead I plan to submit them later while adding USB host support. I've collected all patches and pushed a complete review branch here[1], for people who interested to test easily, which include DTS and necessary changes, other patches may still need to improve, but sufficient for verifying the functionality.
