    Subject[PATCH 5.9 598/757] arm64: dts: mt8173-elm: fix supported values for regulator-allowed-modes of da9211
    Date
    From: Dafna Hirschfeld <dafna.hirschfeld@collabora.com>

    [ Upstream commit 9d955478a89b4a1ff4e7442216f2822dee8fde73 ]

    According to the datasheet the allowed modes for the da9211
    regulator are sync and auto mode. This should be changed in the
    devicetree. This also fix an error message
    'BUCKA: invalid regulator-allowed-modes element 0'
    since value 0 is invalid.
