Subject: ARM: dts: at91: add new compatibility string for macb on sama5d3
X-Git-Tag: v4.14.77~55
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=18918ed70db940b22aad40068a8e20749e5fee74;p=users%2Fjedix%2Flinux-maple.git
ARM: dts: at91: add new compatibility string for macb on sama5d3
[ Upstream commit 321cc359d899a8e988f3725d87c18a628e1cc624 ]
We need this new compatibility string as we experienced different behavior
for this 10/100Mbits/s macb interface on this particular SoC.
Backward compatibility is preserved as we keep the alternative strings.
