Hey Pierre,
Since you are still working on the fixes, I guess this can sneak in before.
The machine drivers are typically low hanging in terms on complexity so we
can merge this first followed by the rework you are doing. I think that part
will still take a bit to stabilize and cleanup.

the update goes out this afternoon, working on it, does this patch
really need to 'sneak in'?

This seems to have got buried with all the Kconfig fixes and reworks? I
was expecting a resend based on those given this discussion but that
didn't seem to ever happen.

We have a small set of corrections to enable SOF to use this machine
driver (mainly to remove hard-coded routes that can be handled by
topology). The plan as I understand it is to first have Liam provide the
SOF core, and in a second step provide all the machine driver updates -
including this one.
