The i.MX31 Freescale's BSP does not have asoc support, just an interface for MC13783 (a Power Management IC from Freescale with integrated audio interface). The wolfsonmicro's tree is the only one that have support to asoc but it does not compiles using the mentioned steps. Am I missing something or may be these drivers broken?
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.
