Hi everyone,

Here are some patches that enable USB3 on RK3328 SBCs that I own. The
changes are quite straightforward, except for the NanoPi R2S, which
has a USB3 Ethernet chip attached. I am aware that there's already a
patch [1] for that. This is my spin on things using the USB device
binding, with comments on how the USB ports are arranged, that I had
done but couldn't find the time to send out.

The last patch also results in some warnings from checkpatch.pl:

    WARNING: DT compatible string "usbbda,8153" appears un-documented -- 
	check ./Documentation/devicetree/bindings/
    #88: FILE: arch/arm64/boot/dts/rockchip/rk3328-nanopi-r2s.dts:398:
    +               compatible = "usbbda,8153";

    WARNING: DT compatible string vendor "usbbda" appears un-documented -- 
	check ./Documentation/devicetree/bindings/vendor-prefixes.yaml
    #88: FILE: arch/arm64/boot/dts/rockchip/rk3328-nanopi-r2s.dts:398:
    +               compatible = "usbbda,8153";

At least the first warning should be covered by the USB device binding

    Documentation/devicetree/bindings/usb/usb-device.yaml

while we probably should add an exception to vendor-prefixes.yaml for
the second warning.

Please let me know what you think.


Regards
ChenYu
