The microphone and dirana3 connection is like below:

 

Microphone             -->   Dirana3

-------------------------------------------------------

MICIN_D3_ADC2_P -> SAF775x: ADC2_IN  

MICIN_D3_ADC2_N-> SAF775x: ADC2_REF 

 

and Microphone audio will output from Dirana3: IIS_SD_OUT0  to SOC part.

 

my question is:

How to configure the dirana3 to make sure the microphone source can route from ADC2_IN/REF to IIS_SD_OUT0 ?

in another words: How to  do configuration of the dirana#3 to support MIC -> dirana -> SOC ?
