Hum, I'm not sure to follow you here. In a subsequent patch, I change
the Armada 370 DB audio complex DT description to use the
simple-audio-card DT binding, which makes the Armada 370 DB audio
machine driver irrelevant.

Of course, this means that if someone uses an old Armada 370 DB Device
Tree with a new kernel, it will no longer. But I believe this is kind
of expected for this specific case: when we originally introduced the
Armada 370 DB audio support, we knew a proper DT binding to describe
sound complex was arriving, and therefore the Armada 370 DB audio
machine driver was only a temporary solution until the pure DT solution
was available.

Therefore, with the agreement of the mvebu maintainers, I'd like to be
allowed to break the DT backward compatibility here, and get rid of
this audio machine driver which would otherwise have no users left.

Thanks!

Thomas
