Thierry Reding looks
at Tegra support in Linux 4.7. “The XUSB driver has been
under development for a ridiculously long time. One of the reasons is that
it relies on the XUSB pad controller to configure its pins as required by
the board design. The XUSB pad controller is very likely one of the
least-intuitive pieces of hardware I’ve ever encountered, and the attempts
to come up with a device tree binding to describe it have been very
numerous. We did finally settle on something earlier this year and after
the existing code was updated for the new binding, we’re finally able to
support super-speed USB on Tegra124 and later.” (Thanks to Martin Michlmayr)
