    Subject[PATCH 4.18 099/135] ARM: dts: at91: add new compatibility string for macb on sama5d3
    Date
    4.18-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Nicolas Ferre <nicolas.ferre@microchip.com>

    [ 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.
