The McBSP driver currently supports TDM mode (DSP mode) up to 16 channels.
It should work out of box.
Take a look at the following drivers:
sound/soc/omap/omap-mcbsp.c
sound/soc/codecs/twl4030.c
sound/soc/omap/omap3beagle.c

for reference. The Beagle have twl4030 codec and it is possible to use
playback with 4 channels.
