What for?

It is used by the driver to generate a unique firmware name.
Basically we need to know which controller instance we
are as each controller has a different firmware which needs
to be loaded.

Rob did say that having a index type property is undesirable
over here, see my reply at the bottom
http://www.spinics.net/lists/devicetree/msg92529.html.

However I can't think of any other useful properties we could add
to derive this information.

The name should be "dma-controller", not "fdma-app".

Ok will fix in v3

Maybe change the compatible string to "st,snd-uni-player"?

Just checking the upstream driver which got merged for v4.3
and the compatible has changed to "st,sti-uni-player" so I
can update the DT doc example to use this in v3.

The string you use here would not be acceptable for a binding.

Presumably it is the use of "underscores" in the compatible which
is not allowed? Is that correct?

Peter.
