[alsa-devel] Problem compiling soc - imx31 and wm8753

[Marcelo Utikawa da Fonseca]

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?
