Second, how about this binding for the virtual sound node? It would be a root-level node.

    sound-devices {

                    playback-dma = &dma00;

Make sure you also have a "compatible" property to uniquely identify the design. You could use the toplevel board one but I'd rather keep a separate one here. I've seen case where the exact same base board may have different sound components (because they are dautherboards for example, but there's a few other cases).
