    Subject[PATCH 5.3 002/105] arm64: tegra: Fix active-low warning for Jetson TX1 regulator
    Date
    From: Jon Hunter <jonathanh@nvidia.com>

    commit 1e5e929c009559bd7e898ac8e17a5d01037cb057 upstream.

    Commit 34993594181d ("arm64: tegra: Enable HDMI on Jetson TX1")
    added a regulator for HDMI on the Jetson TX1 platform. This regulator
    has an active high enable, but the GPIO specifier for enabling the
    regulator incorrectly defines it as active-low. This causes the
    following warning to occur on boot ...

    WARNING KERN regulator@10 GPIO handle specifies active low - ignored

    The fixed-regulator binding does not use the active-low flag from the
    gpio specifier and purely relies of the presence of the
    'enable-active-high' property to determine if it is active high or low
    (if this property is omitted). Fix this warning by setting the GPIO
    to active-high in the GPIO specifier which aligns with the presense of
    the 'enable-active-high' property.
