Nice to see that work almost out of the box :)

BTW, I just noticed that sound/soc/omap/Kconfig has depends on
OMAP_MUX. The OMAP_MUX option will be dropped for mach-omap2
for v3.14, so you may want to take a look at that too. If there
really is a dependency, that should be handled using
pinctrl-single for the .dts entries.

Regards,

Tony

There is actually dependency but only on N810 which needs to remux 4
pins from EAC to McBSP2. I'll try to keep my eye on it but don't let
that block your cleanup work.

Thanks, meanwhile I'll queue your beagle audio fix.
