+Subject: arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet driver
+
+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.
