| RK3328 has one USB 3.0 OTG controller which uses DWC_USB3 |
| core's general architecture. It can act as static xHCI host |
| controller, static device controller, USB 3.0/2.0 OTG basing |
| on ID of USB3.0 PHY. |

| 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. You've been warned. |
