You don't really need to preserve my copyright here.  It will not

"fsl," is not appropriate as the TQM5200 is not a freescale product.
We need a new abbreviation for tq-components.

I think we're moving to the convetion of naming these nodes
"soc@<addr>" now.  (You can drop the 5200 for the node name)
