The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit connections. It is very similar to the device found in the Allwinner H3, but lacks the internal 100 Mbit PHY and its associated control bits. This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps it disabled at this level.

Do you actually need that for all the boards, or only a few of them? Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
