OK, sorry... The problem in a sense is that the codec supports three different modes: BT, FM RX and FM TX. All digital audio goes over a single McBSP connection. The BT part handles the audio routing, which is completely external to the radio driver and this codec. And the user of the codec is in principle responsible for keeping the codec mode in sync with the route setting. And the soc_card driver needs to know the setting also to do its thing.
Which is...
You've still not provided any information about what use this will be put to.
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.
