Hi All,


We have our audio connection around the i.MX6 as below.




Here, we are trying to use audio port 6 as a transmitter (master)  and receiver (slave)  simultaneously.


AUD6_RX - needs to be a slave and receives I2S audio from INAP375R chip.

AUD6_TX - needs to be an I2S master and will push I2S data to an audio codec ( SGTL5000).


Please note that we have connected two different devices to TX and RX lines of same audio port.

Is this configuration supported/allowed  from both HW and SW (Linux) perspective?


Thank you for your support!
