My machine driver contains the following structures:

---
static struct snd_soc_dai_link edb93xx_dai = {
	.name		= "CS4271",
	.stream_name	= "CS4271 HiFi",
	.platform_name	= "ep93xx-pcm-audio",
	.cpu_dai_name	= "ep93xx-i2s",
	.codec_name	= "cs4271-codec",
	.codec_dai_name	= "cs4271-hifi",
	.ops		= &edb93xx_ops,
};

static struct snd_soc_card snd_soc_edb93xx = {
	.name		= "EDB93XX",
	.dai_link	= &edb93xx_dai,
	.num_links	= 1,
};
---

And all other machine SoC drivers contain similar...
If instead I'll write 
.codec_name = "spi0.0",

it will be strange... However it can work...
