I already tried DPCM with the kirkwood audio subsystem. It just ask to
add a 'system' DAI in kirkwood-i2s. The card is defined as:

- link 0:
	CPU: 'system' (kirkwood new DAI)
	CODEC: 'dummy'
	front-end
- link 1:
	CPU: 'i2s' (kirkwood)
	CODEC: 'i2s-hdmi' (tda998x codec)
	back-end
- link 2
	CPU: 'spdif' (kirkwood)
	CODEC: 'spdif-hdmi' (tda998x codec)
	back-end
- link 3
	CPU: 'spdif' (kirkwood)
	CODEC: 'dit-hifi' (spdif codec)
	backend

with the routes (simple-card format):

	"I2S Playback",   "System Playback",
	"SPDIF Playback", "System Playback",
        
 	"hdmi-out",     "I2S Playback",
 	"hdmi-out",     "SPDIF Playback",
	"spdif-out",    "SPDIF Playback";

This works, but the HW constraints of the sinks are not handled, so,
all backends are always activated for any format/any rate.
