Hi Jean Thank you for your feedback > According to Documentation/devicetree/bindings/graph.txt section > "Links between endpoints", the endpoint/remote-endpoint links are > bi-directional and describe the physical links: the audio port of the > codec is connected to the audio controller and reverse. > There is no reverse link from the codec to the 'simple-card'.

My assumption was video/audio are using same port, but indeed we need to care about more. But, if we need to describe both "video port" and "audio port" separately in graph, simple-card side doesn't need graph style IMO. Because normal phandle style (= non graph style) is working already. I thought that describing both "video" and "audio" is too much. -> assume that video/audio can share same port -> this patch -> but thoughtless :P I'm not sure, but do you think snd_soc_get_dai_name()::of_xlate_dai_name can works for us ? My concern is if audio side need to care/support "formal" graph style, I think all cpu/codec/card driver (and soc-core too ?) need to be updated, but it is too much for me. if fake graph style (like this patch) is OK, I'm happy to hack it more.
