The Google Tensor gs101 SoC embeds a DWC3 USB 3.1 DRD controller.
This patch series enables the existing dwc3-exynos glue layer to work on
this SoC.

The Exynos-based Google Tensor gs101 SoC has a DWC3 compatible USB
controller and can reuse the existing Exynos glue. Update the dt schema
to include the google,gs101-dwusb3 compatible for it.

The Exynos-based Google Tensor gs101 SoC has a DWC3 compatible USB
controller and can reuse the existing Exynos glue. Add the
google,gs101-dwusb3 compatible and associated driver data. Four clocks
are required for USB for this SoC:
* bus clock
* suspend clock
* Link interface AXI clock
* Link interface APB clock
