Can you explain in a bit more detail what this does exactly? Is this for channel to slot mapping?
Yes, it is for channel to slot mapping, and it is not only for 8 channels mapping, but also in 2, 4 and 6 channels mapping. If we want to use the 2 channels in the stereo2 adc path, we need to set the setting to item "2/1/3/4" or "2/3/1/4".
