Also, for most of the devices of the same DAI link, they use the same DAI formats, but I have found some drivers like : "sound/soc/pxa/magician.c" and "sound/soc/s6000/s6105-ipcam.c", etc, may have different DAI format settings for some reasons(maybe some formats are the CPU/Codec devices default setting that it needn't set it here or others). I think maybe this is also the reason why the simple-card has common DAI format and CPU/CODEC private DAI formats at the same time.
