As you know, sometimes maybe we only need set the timing from the processor, and codec just only need tx/rx data; So there do not need the codec driver. After browser the code, there have NO such a dummy codec driver; and for soc-core, there have not such flags to support this situation. Only what i get is sound/soc/codecs/spdif_transciever.c, but it's specific for TI's DaVinci platform. I want to get the right direction, so here have some works or discussing for that? Thx, Leo Yan
