Yes it is:
you must specify the first precise SoC needing/implementing it:
"cdns,zynqmp-gem-mdio" or "xlnx,zynq-gem-mdio" or anything looking like
this.
So, if an Atmel implementation is slightly different, we can still use
our own "atmel,sama5d2-gem-mdio" or "cdns,sama5d2-gem-mdio"
compatibility string.
On the other hand, if it's strictly the same, we can use the
"xlnx,zynq-gem-mdio" compatibility without any problem...
