Actually, I don't know the linux-rockchip@lists.infradead.org before.
I'll add the list in CC next patch version.
Thanks~

I have already prepared a new 
Documentation/devicetree/bindings/usb/rockchip,dwc3.txt,
But considering that rockchip,dwc3.txt should contains phys node 
description which are
not ready yet, so I don't add the dt-bindings patch here.
Is it better to add the dt-bindings patch(rockchip,dwc3.txt) without 
phys node description here?
If it is, I'll add  rockchip,dwc3.txt next patch verison.

And I have some doubts about the name format of the usb dwc3 documents.
I notice that there are at least two types of name format:
1. dwc3-xx.txt  (e.g. dwc3-st.txt )
2. xx, dwc3.txt (e.g. qcom,dwc3.txt)

Which one do you prefer?
