So the code should be:
{"MIC_IN", NULL, "Mic Bias}, /* mic bias --> mic_in */ {"Capture Mux", "MIC_IN", "MIC_IN"}, /* mic_in --> adc_mux */-+ {"Mic Bias", NULL, "MIC_IN"}, /* mic_in --> mic bias */ -+ {"Capture Mux", "MIC_IN", "Mic Bias"}, /* mic bias --> adc_mux */
and platform code
{"Mic Bias", NULL, "MIC"},
{"MIC_IN", NULL, "MIC"},No, the bias should be a supply for the microphone - ensuring that this happens is the whole point of the patch I sent the other day.
The "MIC" above is confusing. I guess the following that I have in machine driver might be a little clearer.
{"Mic Bias", NULL, "Mic Jack"}, {"MIC_IN", NULL, "Mic Bias"},
And I need to present it in device tree though.
