Hi Rob, Mark Thank you for your feedback > I need to see how you want to use this. I'm not completely convinced > this is necessary as the port number should be meaningful.

Yes, as you pointed, sound side (= ALSA SoC) will use generic driver for sound card which needs to know its total port number. Then, these patches are needed. I posted OF graph part only this time, but of course I have total full-set in my local environment. But these are ... 1) cleanup current generic sound driver (= almost 30 patch) 2) OF graph new feature (= this patch-set) (= almost 10 patch) 3) OF graph base generic sound driver (= almost 30 patch) - ... I'm posting 1) part to ALSA SoC ML, 2) part to this ML. 1) will take more long term >> Mark ?? If you want to see this patch-set together with use case, then 3) is needed. If so, I will merge 2) and 3), and post these to this ML and ALSA SoC ML. Is it OK for you ? >> Rob, Mark I don't know how to handle it, but I can follow your opinion > In general, all these helpers look okay if you have a user for them. Thanks. As I explained above, it is based on 1) part, but it will takes more long term. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
