ASoC: audio-graph-card2: add DPCM support This patch adds DPCM support to audio-graph-card2. It uses "dpcm" node (= D), needs to have routing (= A), need to indicate both FE/BE at links (= B, C). dpcm ports@0 is for FE (= B), port@1 is for BE (= C). remote-endpoint can use both Single/Multi connection.

ASoC: audio-graph-card2: add Codec2Codec support This patch adds Codec2Codec support to audio-graph-card2. It can use Codec2Codec but very simple case only for now. It doesn't have "SWITCH" control yet, thus it start automatically when it was probed, and can't stop, so far. Thus it needs to be updated around widgets/routing handling, and you need to understand that it is under experimental. Codec has SND_SOC_DAPM_INPUT() (= IN) / SND_SOC_DAPM_OUTPUT(= OUT) widgets in below case. It is assuming 2channel, S32_LE format for now. It needs to be updated, too. It needs "codec2codec" node (= B), needs to have routing (= A), need to indicate CPU side at links (= X). ports@0 is for CPU side (= X), port@1 is Codec side (= Y).
