Hi Pavel,

McASP is having 6 channels like McASP_AXR[0] to McASP_AXR[5]

i am giving 6 audio inputs to AXR[0] to AXR[6]

Where should i make changes so it will accept all 6 audio inputs.

Can i do it in - ti8168_iis_serializer_direction as

    RX_MODE,    RX_MODE,   INACTIVE_MODE,   INACTIVE_MODE,
