Linking via  snd_soc_dai_link or is there another way to link?

static struct snd_soc_dai_link dspeak01_fabric_dai[] = {
{
	.name = "I2S-0",
	.stream_name = "I2S-0",
	.codec_dai = &pcm1690_dai,
	.ops = &dspeak01_fabric_ops,
},
{
	.name = "I2S-1",
	.stream_name = "I2S-1",
	.codec_dai = &pcm1690_dai,
	.ops = &dspeak01_fabric_ops,
},
};
