    Subject[PATCH 5.9 084/252] ARM: dts: sun7i: bananapi-m1-plus: Enable RGMII RX/TX delay on Ethernet PHY
    Date
    From: Chen-Yu Tsai <wens@csie.org>

    [ Upstream commit f94f78bd93f567c022f594589dbeecdf59931365 ]

    The Ethernet PHY on the Bananapi M1+ 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: 04c85ecad32a ("ARM: dts: sun7i: Add dts file for Bananapi M1 Plus board")
