This is the first time I have heard of channel swapping related to
capture on OMAP platforms.
In playback case we can still have corner cases, when channels would
swap/shift, but in capture?
The only thing that I can think of is FIFO overflow, when odd number of
word got discarded, so from application point the channels would swap.
