    Subject[PATCH 5.4 052/158] ARM: dts: sun6i: a31-hummingbird: Enable RGMII RX/TX delay on Ethernet PHY
    Date
    From: Chen-Yu Tsai <wens@csie.org>

    [ Upstream commit e76724153f5b4539802cc21b2c6131058668a1c6 ]

    The Ethernet PHY on the A31 Hummingbird 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").
