It can act as static xHCI host +controller, static device controller, USB 3.0/2.0 OTG basing +on ID of USB3.0 PHY. + +Signed-off-by: William Wu <william.wu@rock-chips.com> +Signed-off-by: Leonidas P. Papadakos <papadakospan@gmail.com> + +--- + +NOTE: This binding still has issues. From the original thread: + +the rk3328 usb3-phy has an issue with detecting any plugin events +after a previous device got removed - see the inno-usb3-phy driver +in the vendor kernel. + +The current state is good-enough for enabling the USB3 attached LAN +port of the NanoPi R2S. However, it might explode depending on your +use-case.
