Unfortunately I don't know where to look. 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...

In kernel dmesg I have following:
