   4 Subject: ARM: dts: at91: add new compatibility string for macb on sama5d3
   5

   8 [ Upstream commit 321cc359d899a8e988f3725d87c18a628e1cc624 ]
   9
  10 We need this new compatibility string as we experienced different behavior
  11 for this 10/100Mbits/s macb interface on this particular SoC.
  12 Backward compatibility is preserved as we keep the alternative strings.
