Subject: [PATCH 2/2] usb: dwc3: exynos: add support for Google Tensor gs101
Date: Tue, 23 Apr 2024 21:19:46 +0100 [thread overview]
Message-ID: <20240423-usb-dwc3-gs101-v1-2-2f331f88203f@linaro.org> (raw)
In-Reply-To: <20240423-usb-dwc3-gs101-v1-0-2f331f88203f@linaro.org>
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
