Subject: [PATCH 3/3] riscv: dts: spacemit: Enable USB3.0 on BananaPi-F3
Date: Sat, 01 Nov 2025 17:03:27 +0800 [thread overview]
Message-ID: <20251101-k1-usb3dts-v1-3-dd2660e5740b@linux.dev> (raw)
In-Reply-To: <20251101-k1-usb3dts-v1-0-dd2660e5740b@linux.dev>
Enable the DWC3 USB 3.0 controller and its associated usbphy2 on the
Banana Pi F3 board.
The board utilizes a VLI VL817 hub, which requires two separate power
supplies: one VBUS and one for hub itself. Add two GPIO-controlled
fixed-regulators to manage this.
