The ESAI and SSI hardware are totally different.  SSI gives you a
playback and a record stream in an I2S, or I2S like, interface.  A
stream is mono or stereo. ESAI has IIRC up to six output and four
inputs streams.  Each stream is in parallel on the same clock, and can
have one or more channels. 

Are these channels on the same wire in a time-division multiplexing, or on
six different wires?  If it's a TDM, then the SSI can actually do this
using "network mode", but I don't enable that in the driver, since it's
not really I2S compliant.

Well, this point is not really relevant to the discussion.
