Hi Mark Brown, Now, I am trying to move atmel audio part to DT support. I meet the following issue.

Atmel audio part has three platform device: -> atmel ssc: ssc library (different SOC has different number) -> atmel ssc dai: dai for audio -> atmel pcm: for pdc or dma transfer (now only support pdc, dma support will add soon)

In DT support kernel, I don't find any similar case. So, if I want to keep ssc as library, and use dai to register pcm. Then the dts file will like: ---<8--- ssc0: ssc@fffbc000 { status = "okay"; };

dai0: dai { compatible = "atmel,atmel-ssc-dai"; };

sound { compatible = "atmel,at91sam9g20-audio"; atmel,model = "wm8731 @ sam9g20ek";

             atmel,audio-routing =
                     "Ext Spk", "LHPOUT",
                     "Int Mic", "MICIN";

             atmel,audio-codec = <&wm8731>;
             atmel,dai = <&dai>;

}; --->8---

Would this be OK? If not, may I add some code for ssc which dedicate for audio into sound/soc/atmel (using audio-ssc and ssc to distiguish which dedicate for audio, which used for ssc library)? This will broken the exist code for audio (only sam9g20-wm8731). Any suggestion?
