Though, if the difference between the two units is the availability of
SPDIF support, then we shouldn't encode the channel number, but instead
the availability of SPDIF, i.e:

	audio0 {
		reg = <... ...>;
		compatible = "marvell,kirkwood-audio";
		marvell,has-spdif;  

Agree, if you make it "marvell,has-spdif-in" and "marvell,has-spdif-out"
Dove has either i2s-only or i2s+spdifo, kirkwood has i2s+spdifo+spdifi
for the one audio controller available. Can't tell for Armada 370.

BTW, you might have followed some of the DT discussions with Mark
before; as he insists on having a separate sound card node, he might
argue that above property should be part of that node instead.

Yes. For the Cubox, the card will be described by something like:

	sound {
		compatible = "simple-audio";
		audio-controller = <&audio1>;
		audio-codec = <&spdif>;
		codec-dai-name = "dit-hifi";
	};

with:

	spdif: spdif {
 		compatible = "linux,spdif-dit";
	};

Then, the audio driver will know about s/pdif on the first open.
