Hi,
This is my spin on enabling Ethernet on the A83T. It consists of
Corentin's dtsi patch plus my board level patch. There's nothing
really special about them.

The dwmac-sun8i is an ethernet MAC hardware that support 10/100/1000 speed.
This patch add support for it on the Allwinner a83t SoC Device-tree.
This patch add the emac device node and the related RGMII pins node.

The Cubietruck Plus has a Realtek RTL8211E RGMII PHY tied to the EMAC.
The AXP818 PMIC's regulators provide main power and secondary signaling
voltages to the PHY. The latter is always on, as it also supplies the
pingroup on the SoC, which has other uses.
The Bananapi M3 has a Realtek RTL8211E RGMII PHY tied to the EMAC.
The AXP818 PMIC's SW regulators provides power to the PHY.
This patch enables Ethernet with the EMAC on both these boards by
enabling the emac node and setting all the required properties.
A proper ethernet alias is added as well.
