connect a "loose" device to a OFW/FDT node (and then use mii_fdt)?

Hi,

I have a device which has its own ivars and is not created from OFW/FDT.

The parent(parent(dev)) was but FDT does not fully represent the logic
of it and we need to create the intermediate device *sigh*

I tried to put ASCII art below (try a plain text view if needed).

Is there any way to connect this "mac" device to its relevant node in FDT
(continuing the "tree" there) and then use mii_fdt to attach (doing
all the PHY stuff and references)?

/bz

So looks something like this:

  X (ofw/fdt/simplebus node/device)
  |
  +--- interim dev (not in FDT created by X)
       |
       +----- mac dev (in FDT but created as child of 'interim dev' and not out of ofw/fdt/simplebus)
                |
                +---- miibus(_fdt if possible)
                         |
                         +------ PHY
