Then what is wrong with my binding code? If I take out the
registration my bind fails.

static struct snd_soc_dai_link pcm030_fabric_dai[] = {
{
	.name = "AC97",
	.stream_name = "AC97 Analog",
	.codec_dai = &wm9712_dai[WM9712_DAI_AC97_HIFI],
	.cpu_dai = &psc_ac97_dai[MPC5200_AC97_NORMAL],
},
{
	.name = "AC97",
	.stream_name = "AC97 IEC958",
	.codec_dai = &wm9712_dai[WM9712_DAI_AC97_AUX],
	.cpu_dai = &psc_ac97_dai[MPC5200_AC97_SPDIF],
},
};

static __init int pcm030_fabric_init(void)
{
	struct platform_device *pdev;
	int rc;

	if (!machine_is_compatible("phytec,pcm030"))
		return -ENODEV;

	card.platform = &mpc5200_audio_dma_platform;
	card.name = "pcm030";
	card.dai_link = pcm030_fabric_dai;
	card.num_links = ARRAY_SIZE(pcm030_fabric_dai);

	device.card = &card;
	device.codec_dev = &soc_codec_dev_wm9712;

	pdev = platform_device_alloc("soc-audio", 1);
	if (!pdev) {
		pr_err("pcm030_fabric_init: platform_device_alloc() failed\n");
		return -ENODEV;
	}

	platform_set_drvdata(pdev, &device);
	device.dev = &pdev->dev;

	rc = platform_device_add(pdev);
	if (rc) {
		pr_err("pcm030_fabric_init: platform_device_add() failed\n");
		return -ENODEV;
	}
	return 0;
}
