    Subject[PATCH 5.13 301/351] arm64: dts: qcom: c630: Add no-hpd to DSI bridge node
    Date
    From: Stephen Boyd <swboyd@chromium.org>

    [ Upstream commit c0dcfe6a784fdf7fcc0fdc74bfbb06e9f77de964 ]

    We should indicate that we're not using the HPD pin on this device, per
    the binding document. Otherwise if code in the future wants to enable
    HPD in the bridge when this property is absent we'll be enabling HPD
    when it isn't supposed to be used. Presumably this board isn't using hpd
    on the bridge.
