Hi Mark Cc Sameer > Having an audio-graph-card2 isn't ideal but may be required at least > during development :/ Ideally we'd be able to have the new driver parse > both binding formats (or rather, have the new binding format be new use > cases for the same binding format) and only use -card2 while it's in > development. If you want to update current audio-graph-card without creating new audio-graph-card2, I'm OK about it. But need adjusting / agreement. Current audio-graph-card "DSP" user is only me, and I'm using it only locally. Thus upstream doesn't get damage if I removed "audio-graph-scu-card" (= DSP use case) support. OTOH, Sameer is posting patch for "-cc-" support. If it was accepted and he used it on upstream (= on tegra), keeping compatibility will be very difficult and/or code will be very confusable. If Sameer can OK and wait new audio-graph-card, maybe we have no compatibility issue. But in such case, 1st version of new audio-graph-card might be not enough for him. Sameer need to waiting / testing / adjusting / etc, etc... Thank you for your help !! Best regards --- Kuninori Morimoto
