What does this mean?  Changing a number into a non-obvious string (Why
"pseudo"?  Why does the UIO user care that the config came from the device
tree?) just to avoid setting off Greg's version number autoresponse isn't
really helping anything.

Greg's comment notwithstanding, I really don't think this belongs in the
device tree (and if I do get overruled on that point, it at least needs a
binding document).  Let me try to come up with a patch for dynamic allocation.
