The PowerPC side isn't without fault too. PowerPC still doesn't have a
good way to load the fabric/machine driver.

I'm finding it difficult to square these two statements - from an ASoC
point of view the main thing this patch is doing is adding a machine
driver and that's not something that's going to go away.

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.

It's purely an *OF Device Tree* problem.  PowerPC isn't the only
platform using the device tree.  :-)
