This series adds support for the second Ethernet controller found on the
Allwinner A523 SoC family. This controller, dubbed GMAC200, is a DWMAC4
core with an integration layer around it. The integration layer is
similar to older Allwinner generations, but with an extra memory bus
gate and separate power domain.

Patch 1 adds a new compatible string combo to the existing Allwinner
EMAC binding.

Patch 2 adds a new driver for this core and integration combo.


Thanks
ChenYu
