18 and thus contains any logic common to all its lanes. Each lane can be
21 Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
22 super-speed USB. Other lanes are for various types of low-speed, full-speed
23 or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
24 contains a software-configurable mux that sits between the I/O controller
25 ports (e.g. PCIe) and the lanes.
27 In addition to per-lane configuration, USB 3.0 ports may require additional
28 settings on a per-board basis.
30 Pads will be represented as children of the top-level XUSB pad controller
31 device tree node. Each lane exposed by the pad will be represented by its
32 own subnode and can be referenced by users of the lane using the standard
