The future introduction of orphan nodes for addons device-tree will lead
to more than one tree in the addons data. Those trees will be:
  - the classical root tree starting at the root node
  - trees related to orphan nodes  

This doesn't make sense to me.  The new function still just takes a
single path, nothing to specify which tree that path is looked up in.

You can probably guarantee that labels and phandles are unique across
all the trees.  Not paths, though.

Paths can be unique across all trees. The tree needs to be indicated in the
path. Starting by '/' is the root tree.

Oh, ok.  That wasn't clear from this patch, and I must have missed it
in my cursory look at the later patches.  I had the mistaken
impression this just looked for the same path in each orphan tree.

For orphans, I proposed "$<orphan_name>/<path>" in patch 64 introducing
references by path for orphan nodes and so, for orphan trees.

Best regards,
Hervé
