SPDIF is used for HDMI audio.

arch/arm:
Seaboard registers an spdif-dit platform device, but that seems to be the


sound/soc:
As far as I can see, the only thing that needs to be done is to setup a second
link in paz00.c (make paz00_alc5632_dai an array and maybe rename, and set
num_links to ARRAY_SIZE(paz00_alc5632_dai)). The device used by seaboard
is:

	{
		.name = "SPDIF",
		.stream_name = "spdif",
		.codec_name = "spdif-dit",
		.platform_name = "tegra-pcm-audio",
		.cpu_dai_name = "tegra-spdif",
		.codec_dai_name = "dit-hifi",
		.ops = &seaboard_spdif_ops,
	},

I'll take a closer look at it tomorrow, and hopefully
provide a complete patch, so that I have HDMI audio.
