Planning to send a fix for that? Reviewed-by: Konrad Dybcio <konrad.dybcio@linaro.org> Konrad

I don't have boards suitable for testing, so let's just leave it. Best regards, Krzysztof

The SWR2 Soundwire instance has 1 output and 4 input ports, so for the headset recording (via the WCD9385 codec and the TX macro codec) we want to use the next DAI, not the first one (see qcom,dout-ports and qcom,din-ports for soundwire@6d30000 node). Original code was copied from other devices like SM8450 and SM8550. On the SM8450 this was a correct setting, however on the SM8550 this worked probably only by coincidence, because the DTS defined no output ports on SWR2 Soundwire. This is a necessary fix for proper audio recording via analogue microphones connected to WCD9385 codec (e.g. headset AMIC2).
