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 Signed-off-by: André Draszik <andre.draszik@linaro.org> --- drivers/usb/dwc3/dwc3-exynos.c | 9 +++++++++ 1 file changed, 9 insertions(+)
