It depends on how many clocks and DMA engines are used, and if there are
multiple ones, if and how they are synchronized.

What SoC?

If there is a single SoC, it's likely that all channels are indeed
synchonrized.

Why I²S?  Do you already have a SoC or a bunc of codecs that you want
to use?  What are your constraints?
