Note: This patch may break MDIO functionallity of some old 
Freescale's SoC
until Freescale will fix their device tree files. Basically, every 
device tree
which contains an mdio device that is compatible to "fsl,gianfar-tbi" 
should be
examined.

I generally agree with this statement except that without this patch, 
almost ALL of Freescale's SoC that uses "fsl,gianfar-tbi" are broken, 
including the older ones. At least this patch fixes some of the device 
trees. Because I'm not working at Freescale, I have a very limited 
access to a few SoC which I could test this patch on. I think it is 
Freescale's responsibility to release a complementary patch to fix the 
rest of the SoC device trees.
