Yes, sorry I didn't get your point. I guess I tought that it's irrelevant, what
the soc_card driver actually does. But it actually does this:
switch (wl1273_get_codec_mode(codec)) {
case WL1273_MODE_FM_RX:
case WL1273_MODE_FM_TX:
fmt = SND_SOC_DAIFMT_I2S |
SND_SOC_DAIFMT_NB_NF |
SND_SOC_DAIFMT_CBM_CFM;
break;
case WL1273_MODE_BT:
fmt = SND_SOC_DAIFMT_DSP_A |
SND_SOC_DAIFMT_IB_NF |
SND_SOC_DAIFMT_CBM_CFM;
break;
default:
return -EINVAL;
}
r = snd_soc_dai_set_fmt(cpu_dai, fmt);
Cheers,
Matti A.
