Yes, I2S. There's also a couple of I2C busses (one in the northbridge,
probably for the SDRAM config, the other one in the mac-io chip). 

This part of the device tree looks like that:

pci/mac-io
    ...
    /i2c
        /i2c-cereal
    /i2s
        /i2s-a
            /sound
        /i2s-b
    ...
