USB 3.1 (3.2) support in U-Boot?

USB 3.1 (3.2) support in U-Boot?

[Stefan Roese]

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

     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?

Thanks,
Stefan

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
