From: Thierry Reding <treding@xxxxxxxxxx> This is the result of my attempt to come up with a correct binding for the XUSB pad controller found on NVIDIA Tegra SoCs. Note how this is a completely new binding document. The old binding, which we should mark deprecated if we settle on this new one, modelled the device as a pinctrl/PHY hybrid, but it turns out that it's really not much of a pin controller after all. I have a driver, which is pretty much Andrew's work, heavily reworked and put into drivers/phy. I've tested this on Jetson TK1 (for Tegra124) and P2371-2180 (for Tegra210) and I successfully see PCIe, SATA and super-speed USB working on Jetson TK1 as well as super-speed USB on the P2371-2180 (root on NFS and USB 3.0 and USB 2.0 pen drives work fine). Moving the driver into drivers/phy also gives us a trivial way to keep backwards-compatibility by simply keeping the old driver in place and calling into it from the new driver if a legacy DTB is detected. I still need to do a bit of squashing and sorting of the driver patches but I wanted to get this out now because I know Stephen is working on a set of patches to support the XUSB pad controller on Tegra210 in U-Boot and the discussion can hence continue irrespective of the driver code. Note also that this isn't quite complete yet. I've left out most of the HSIC-specific properties for now because there is no user for those in the upstream kernel, so I didn't have an example nor test-case.
