    Subject[PATCH 5.5 003/257] ARM: dts: Fix dm814x Ethernet by changing to use rgmii-id mode
    Date
    From: Tony Lindgren <tony@atomide.com>

    [ Upstream commit b46b2b7ba6e104d265ab705914859ec0db7a98c5 ]

    Commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode")
    caused a regression for dm814x boards where NFSroot would no longer work.

    Let's fix the issue by configuring "rgmii-id" mode as internal delays are
    needed that is no longer the case with "rgmii" mode.
