[PATCH 2/2] usb: dwc3: exynos: add support for Google Tensor gs101

From: André Draszik
Date: Tue Apr 23 2024 - 16:20:18 EST


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
