Hi Board Designers,
Refer below FAQs:

Please refer below inputs i received from the expert.
The proposed setup looks ok. Since not details on the communication format have been provide, just some comments on the configuration.
MCASP0 * Bluetooth and Tuner must be running with the same format (TDM/I2S/etc) and word size setup and are synchronized with the bit clock and frame Sync
MCASP2 * Codec and amplifier must be running with the same format (TDM/I2S/etc) and word size setup and are synchronized with the bit clock and frame Sync
Two devices can be connected to McASP. It is recommended to follow good layout practices when routing the bit clock. Use the IBIS model to check signal integrity.
The required configuration is valid. Please use the SysConfig tool to ensure correct peripheral/IOSet configuration.
Synchronous Transmit and Receive Operations -
When the MCASP_ACLKXCTL[6] ASYNC bit is written to 0b0, the transmit and receive sections operate
synchronously to the transmit section clock and transmit frame sync signals.
Though Rx section may have a different data format, it has to be configured to have the same slot size than
the transmit section one.

Each McASP serializer can be set as either Rx, Tx, or none. You can see an example within k3-j721e-common-proc-board.dts where mcasp10 has 4 serializers set as Tx and 3 serializers set as Rx.
