    Subject[PATCH 5.10 556/663] dts64: mt7622: fix slow sd card access
    Date
    From: Frank Wunderlich <frank-w@public-files.de>

    commit dc2e76175417e69c41d927dba75a966399f18354 upstream.

    Fix extreme slow speed (200MB takes ~20 min) on writing sdcard on
    bananapi-r64 by adding reset-control for mmc1 like it's done for mmc0/emmc.

    Fixes: 2c002a3049f7 ("arm64: dts: mt7622: add mmc related device nodes")
