For I2S mode, data lines for channel 3 to 6 are not routed out of the SoC. i.e FSD SoC has only SDO0 line routed out. SDO1 and 2 are floating pins. So Exynos7-I2S in FSD SoC supports only stereo playback and capture in I2S mode. I'll reword the description in the next patch set to reflect the above information. Thanks, Padmanabhan R.
