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
