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.
