Jon's concern is that there is no straightforward way to build a kernel with
multiple fabric drivers and have the right one chosen via the device tree. This
is just a limitation of the device tree model, and no one has come up with a
good solution yet.
The problem still exists in ASoC V2. However, it's not anything that ASoC
itself needs to be concerned with. It's purely a PowerPC problem.

Wait, I thought it's supposed to be called a fabric driver now? On PowerPC, it
should be called a fabric driver because we already have machine drivers.
