You shouldn't be doing this. The soc-pcm code is *purely* about
managing the interdependencies between the data DMAed from memory and
the external interfaces on a SoC, if you're an off-SoC device then you
should be providing a CODEC driver. This is why you're having trouble
working out how to fit your driver into the frameworks - they're not
designed to do what you're trying to do.

Well, the bigger blocker here is that we don't have any Slimbus support
in the kernel at the minute. I'm hoping to help push that along at the
KS/LPC/LinuxCon conferences at the end of this month.
