Maybe I am mistaken, but I remember Seppo mentioning 4mics worked before this PR - was this with a similar change? @singalsu, can you comment? |

Yes, we got four channels (and four microphones) capture to work already with git master code in UP2. The driver uses only DMIC[0] DAI since the secondary DMIC[1] (FIFO B) support is not finished. It is sufficient for SOF 1.2 to support only the primary multi-channel FIFO with 1/2/4 channels. You may add DMIC[1] related updates as long as the DMIC[0] is not harmed. I would have done this change and other needed later anyway. |

@singalsu are you approving ? |
|
I need to test this first. |

@lgirdwood @singalsu I asked seppo about this dmic[1] and it seems we need more work done before it could work. We may kept it not probe before we finish the work. |
apl and cnl have 2 dmic dai but only probe 1.
Probe all these 2 dmic dais.
