Subject: [PATCH v2 2/3] riscv: dts: spacemit: enable USB3 on OrangePi R2S
Date: Thu, 2 Apr 2026 18:00:06 +0800 [thread overview]
Message-ID: <20260402100007.110201-3-amadeus@jmu.edu.cn> (raw)
In-Reply-To: <20260402100007.110201-1-amadeus@jmu.edu.cn>
Enable the DWC3 USB3.0 controller and its associated PHY on the
OrangePi R2S. The USB regulator provides VBUS for USB2 and USB3
ports, but the USB2 ports are handled by a separate controller.
