Hi All,

does anyone know of the USB 3.1 support status in mainline U-Boot? I've only seen these related patches:

commit d92e866f6008fdd6483735c6fd1ed95c8fdc87b1 Author: Chunfeng Yun chunfeng.yun@mediatek.com Date: Wed Oct 14 15:08:28 2020 +0800

 usb: common: add define of usb_speed_string()

 There is only declaration of usb_speed_string(), but no definition,
 so add it to avoid build error when call it.

With no real functional changes. So has anyone already successfully tested an USB 3.1 controller in recent U-Boot?

I have not tested USB 3.1/3.2 in U-Boot. Maybe Chunfeng did.

I only tested USB 3.2 GEN1 (5G), didn't test USB3.2 GEN2, added this enum just for building pass
