    Subject[PATCH 5.14 037/125] arm64: dts: imx8mm-kontron: Fix polarity of reg_rst_eth2
    Date
    From: Frieder Schrempf <frieder.schrempf@kontron.de>

    commit 6562d6e350284307e33ea10c7f46a6661ff22770 upstream.

    The regulator reg_rst_eth2 should keep the reset signal of the USB ethernet
    adapter deasserted anytime. Fix the polarity and mark it as always-on.

    Anyway, using the regulator is only a workaround for the missing support of
    specifying a reset GPIO for USB devices in a generic way. As we don't
    have a solution for this at the moment, at least fix the current
    workaround.

    Fixes: 8668d8b2e67f ("arm64: dts: Add the Kontron i.MX8M Mini SoMs and baseboards")
