Today, I tried to migrate my ASoC machine driver to 3.8 kernel. But now I'm facing with new problems. For example, there is no option for mcasp interface in bb.org_defconfig. So, when I compiled the kernel and modules, I didn't find the mcasp kernel module and omap spi kernel module. If I try to load my machine driver with cape_manager I'll get this error:

Does anybody has successfully compiled the mcasp0 module, like in 4.1 kernel? Moreover, do you use the offical Beaglebone repo from Github?
