This series introduces support for the USB controller and PHY found on
Google Tensor SoCs (G5 and newer). This includes:

1.  DWC3 Glue Driver: A new glue layer for the Synopsys DesignWare USB 3.0
    controller (DWC3) as integrated into Google Tensor SoCs, including
    hibernation support.
2.  DWC3 DT Bindings: Device Tree binding documentation for the Google
    Tensor SoC DWC3 controller.
3.  USB PHY Driver: A new driver for the Google Tensor SoC USB PHY,
    initially supporting high-speed operations.
4.  USB PHY DT Bindings: Device Tree binding documentation for the Google
    Tensor SoC USB PHY.
