Device tree binding for NVIDIA Tegra XUSB pad controller
========================================================
+NOTE: It turns out that this binding isn't an accurate description of the XUSB
+pad controller. While the description is good enough for the functional subset
+required for PCIe and SATA, it lacks the flexibility to represent the features
+needed for USB. For the new binding, see ../phy/nvidia,tegra-xusb-padctl.txt.
+The binding described in this file is deprecated and should not be used.
+
The Tegra XUSB pad controller manages a set of lanes, each of which can be
assigned to one out of a set of different pads. Some of these pads have an
associated PHY that must be powered up before the pad can be used.
