Hello Peter,
USB3 phy driver "rockchip,rk3328-u3phy" has not been implemented on
upstream linux kernel.
FireflyTeam use the special version of linux that is modified by Rockchip.
(It seems based on linux-4.4)
rockchip,rk3328-u3phy is provided by
https://github.com/FireflyTeam/kernel/drivers/phy/rockchip/phy-rockchip-inno-usb3.c
That's a 404 over here.
If you want to use USB 3.0 with upstream linux, we need to port this
USB3 phy driver from rockchip-linux to upstream kernel, I think.
Best Regards,

Good Afternoon,
Is there a particular reason why the USB3 controller on the rk3328 has
not been enabled?
It's enabled on the TeamFirefly source [0].
I pulled it in to my device tree and have been using a USB3 SSD as my
boot device for over a year now.
If I were to submit the patch, would y'all be open to pulling it in?
