As I say, the drivers rely on code in the Freescale BSP; you may not
have the lastest Freescale BSP.  There is some code here:

	git://opensource.wolfsonmicro.com/linux-2.6-audioplus imx31

but note that this uses ASoC v2 so will definitely require some porting
of the WM8731 driver unless the copy there is already up to date.  That
tree is entirely focused on supporting the WM835x (an audio+PMIC device
comprable to the Atlas which is shipped by default) with the i.MX31ADS.
