Thanks for the idea ... I have set this :
     i2s0: i2s@03830000 {
         status = "okay";
     };

and I get the same problem.

Is there anything else which is required to register the samsun-i2s.0 
driver ?
Can you tell me whether my codec/driver requires any code to register 
the i2s0 ?

I have the following in my driver :
static struct snd_soc_dai_link implant_dai = {
     .name        = "implant bva",
     .stream_name    = "IMPLANT",
     .cpu_dai_name = "samsung-i2s.0",
     .codec_dai_name = "implant-pcm",
     .platform_name = "samsung-i2s.0",
     .codec_name    = "implant-codec",
};

thanks
Matt
