   4 Subject: arm64: allwinner: sun50i-a64: add dwmac-sun8i Ethernet driver
   5
   6 The dwmac-sun8i is an Ethernet MAC that supports 10/100/1000 Mbit
   7 connections. It is very similar to the device found in the Allwinner
   8 H3, but lacks the internal 100 Mbit PHY and its associated control
   9 bits.
  10 This adds the necessary bits to the Allwinner A64 SoC .dtsi, but keeps
  11 it disabled at this level.
