In the device the CPU (s3c6410) has XPCM*0 pins connected to audio card and XPCM*1 pins routed to GSM modem (not sure about that). In the kernel sources I have several s3c_i2s sources. The raw one, then s3c6410_i2s, s3c6410_i2s-v32 and s3c6410_i2s-v40. And they are very different to each other. I am using s3c6410_i2s-v32 as it is used in similar project. Anyway I am not sure which i2s file I should use...
