Thanks for updating this, this looks more future proof for adding
the dra7 related patch.
For the long run, it probably makes sense to add SoC specific
compatible values such as "ti,cpsw-am3350" and so on. Then the
mac address functions can be initialized based on the of_device_id
entry for .data. The wiring is cleary SoC specific here.
So for the purpose of this series, I'm fine with this series,
please feel free to add for this patch:
