    Subject[PATCH 5.11 129/601] ARM: dts: exynos: correct fuel gauge interrupt trigger level on GT-I9100
    Date
    From: Krzysztof Kozlowski <krzk@kernel.org>

    [ Upstream commit 46799802136670e00498f19898f1635fbc85f583 ]

    The Maxim fuel gauge datasheets describe the interrupt line as active
    low with a requirement of acknowledge from the CPU. The falling edge
    interrupt will mostly work but it's not correct.

    Fixes: 8620cc2f99b7 ("ARM: dts: exynos: Add devicetree file for the Galaxy S2")
