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? > ^ permalink raw reply [flat|nested] 24+ messages in thread
