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.
