Sorry, I forgot to remove it from the patch.

BTW, the graph of port should also contain pieces of the audio specific
hardware information as the ones found in the simple-card (clock,
GPIO, ...). This information could be written as generic device node
properties. i.e without any prefix.

I was also wondering about some of these properties, as widgets and
routing. They seem to be software information and Linux specific.
Must these properties appear in the DTs?
