From: Greg Ungerer <g...@uclinux.org> Create a common set of definitions of address and register values for ethernet MII phys. A few of the current ethernet drivers have at least a partial set of these definitions. Others just use hard coded raw constant numbers.
This initial set is copied directly from the allwinner_emac code.
