Reding: What's new for Tegra in Linux v4.7

Thierry Reding looksat Tegra support in Linux 4.7. "The XUSB driver has beenunder development for a ridiculously long time. One of the reasons is thatit relies on the XUSB pad controller to configure its pins as required bythe board design. The XUSB pad controller is very likely one of theleast-intuitive pieces of hardware I've ever encountered, and the attemptsto come up with a device tree binding to describe it have been verynumerous. We did finally settle on something earlier this year and afterthe existing code was updated for the new binding, we're finally able tosupport super-speed USB on Tegra124 and later."
