[PATCH v3 0/3] Add usb3 ctrl node on RK3328 SoCs and enable usb3 host on RK3328 evb

[William Wu]

This series add support for usb3 controller on RK3328 SoCs.
This series don't include usb3 phy patches, and I will try
to submit usb3 phy patches individually later.

Tested on RK3328 evaluation board.

         Could you help to reviewed this patch? According to Heiko's 
suggestion, this patch
         need to be submitted to usb tree or at least get an Ack from you.

         Thank you!

[PATCH v3 2/3] arm64: dts: rockchip: add usb3 controller node for RK3328 SoCs

[William Wu]

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.
