Hello,
I'm currently attempting to get TLV320AIC3104 audio working on our board (Qualcomm mdm9615).
hardware: mdm9615 + TLV320AIC3104
software: yocto 1.6 (linux kernel 3.4.91)
I want to add both platform info and codec info into machine file (linux/sound/soc/msm/mdm9615.c) in linux way. but there are too many snd_soc_dai_link structure . I don't know which one to choose for adding codec info or every one should been changed. hope for your advice , Tks!
specific code as follow.
/* Digital audio interface glue - connects codec <---> CPU */
static struct snd_soc_dai_link mdm9615_dai_ar7[] = {
