I think this relationship is like the current designware.c and 
gmac_rockchip.c, except that the designware driver becomes DWC EQoS. In 
fact, most of the code is the same, because it is the same controller, 
and there are a few differences related to Soc implemented in 
gmac_rockchip.c, this is the purpose of my series of patches, and the 
code must be compatible with the previous Rockchip Socs.
