So, what I'm saying is that it is_impossible_ to drive the TDA998x using
multiple I2S streams which are not produced by the same I2S block.
This is besides the point, but it is possible that one of the multiple
I2S blocks is the bit-clock and frame-clock master to the i2s bus and
the others are slaves to it (banging their bits according to SCLK and WS
of the I2S master). However, in this situation there really is only one
i2s bus with multiple data pins.
Just my 0.02€ to this discussion.
