One of these drivers you can track here:
https://patchwork.kernel.org/patch/3109791/
This is necessary to enable serial console on Saltbay (Merrifield based
platform). But the driver is still being reworked to be upstreamed.

Anyway, upstream those drivers won't work to validate this patch set
we're discussion here. All platform codes are bool (can't be module).
The real purpose of these patches is to make my internal tree to be
equal to upstream. My intention is to upstream *all* internal patches
of Intel MID and temporarily move away from arch/x86/platform/intel-
mid/device_libs/ the platform code from still-on-staging-state drivers.

So, we need a dummy module on upstream to make this code testable.

In case this code is not accepted, I'll will have to maintain 2
official public branches: one with these patches and one without them.

Br, David
