[PATCH v8 3/3] riscv: dts: spacemit: Enable USB3.0/PCIe on OrangePi RV2

[Han Gao]

Enable the DWC3 USB 3.0 controller and its associated usbphy2 on the
OrangePi RV2 board.

The board utilizes a Genesys Logic GL3523 USB3.0 hub.

Define a 3.3v fixed voltage regulator for PCIe and enable PCIe and
PHY-related Device Tree nodes for the OrangePi RV2.

Re: [PATCH v8 0/3] riscv: dts: spacemit: Add PMIC regulators usb pcie

[Vincent Legoll]

[-- Attachment #1: Type: text/plain, Size: 247 bytes --]

Hello Han Gao,


I tested this series applied on top of next-20260403.

It booted properly with rootfs on SATA SSD via USB3 adapter.

So you can add:

Tested-by: Vincent Legoll <legoll@online.fr> # OrangePi-RV2

Find the dmesg attached.

Regards
