Are we saying that what gets transmitted on the bus is neither valid
I2S or DSP mode data? But as you have your custom hardware block in
the middle it interprets this data correctly and converts it to a
regular bus format on the other side that goes to the CODEC?

Yes, essentially there is translation between the two data word edge
triggered ABP (the bcm2835's PCM block) and a Cirrus Logic TDM codec.

Could you please be concrete about what the two formats you're talking
about here are and how these differences are observable on the wire?  I
don't know what "two data word edge triggered ABP" means.
