From: Thierry Reding <treding@xxxxxxxxxx> The XUSB pad controller allows PCIe lanes to be controlled individually, providing fine-grained control over their power state. Previous attempts at describing the XUSB pad controller in DT had erroneously assumed that all PCIe lanes were driven by the same PHY, and hence the PCI host controller would reference only a single PHY. Moving to a representation of per-lane PHYs requires that the operating system driver for the PCI host controller have access to the set of PHY devices that make up the connection of each root port in order to power up and down all of the lanes as necessary.
