I agree that it does not make sense to add configurations that no one else can try and use. The goal is that others can easily try out the IP. I want to provide the FPGA image to others who are interested. It won't be many of course. > Also based on your description where you use evaluation board with FMC > card it is far from any product and looks like demonstration configuration. You are right, it is not product, which is addressed to end users. It is a demonstration configuration for developers. Isn't that valid for all evaluation boards? As a developer I'm very happy if I can do evaluation and development without any vendor tree. I can do that now with the ZCU104. So a big thank you from me for your work! > You can add the same fragment to dt binding example which should be > enough for everybody to understand how your IP should be described. This dt binding example is already there. So a device tree like this won't be accepted? Gerhard
