You have I think three choices for recourse here, any of which should fix your problem: 1.) Remove the /soc/syscon from the DTB you're using 2.) Update your DTB to actually use /soc/syscon, removing the syscon reg from /soc/ethernet and adding a 'syscon =3D <&syscon>' attribute to that node. 3.) Update to r327825 or later and pull new DTS from Linux. If pulling new from Linux is a pain, I can generate a new DTB for you based on what we'll be importing from Linux in a couple weeks. r327825 added support for the new stable emac bindings, so after DTS update this won't break again.
