I think you need to implement the PRCM compliant interrupt config to check for McBSP underflow/overflow.
I have implemented the interrupt handle for IRQ 17 for receive error and underflow/overflow. However, the devices are running for 2 days without channel swapped. I will keep them running.
I'll try to resurrect my Beagle board, since that as well have the twl codec on McBSP2...
I will test it on EVM board as well.
We have tested the element mode for dma_op_mode. It works fine, we don't see any channel swapping in this mode.
Thanks, Ying
