Yes, device associated with the parent node. Something like:

 - edid-phandle - phandle to the EDID handler block; if this property is
  not specified it is assumed that EDID is handled by device described 
  by parent node of the HDMI RX node

Not sure if it is any better than always requiring edid-phandle property,
even when it is pointing to the parent node. We would need a DT maintainer's
opinion on that.
