Ideally you could, but there are some bugs in the way compatible string
in handled and due to this I suspect you need to reorder
cpsw_of_mtable[] to match correctly. Not sure if the bug has been fixed
in recent -rcs. Please check if modifying just this patch works and then
go ahead and post.

Please Cc Benoit Cousson <bcousson@...libre.com> on your next submission
as he is the one who picks up DT patches for OMAP.

Thanks,
Sekhar
