    Subject[PATCH 4.19 39/91] arm64: dts: allwinner: a64: bananapi-m64: Enable RGMII RX/TX delay on PHY
    Date
    From: Chen-Yu Tsai <wens@csie.org>

    [ Upstream commit 1a9a8910b2153cd3c4f3f2f8defcb853ead3b1fd ]

    The Ethernet PHY on the Bananapi M64 has the RX and TX delays
    enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins.

    Fix the phy-mode description to correct reflect this so that the
    implementation doesn't reconfigure the delays incorrectly. This
    happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e
    rx/tx delay config").

    Fixes: e7295499903d ("arm64: allwinner: bananapi-m64: Enable dwmac-sun8i")
    Fixes: 94f442886711 ("arm64: dts: allwinner: A64: Restore EMAC changes")
