    Subject[PATCH 6.0 195/862] drm/amd/display: Enable 2 to 1 ODM policy if supported
    Date
    From: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com>

    commit 54fae65ff469a79fc0ca46f480c4e7fce50f3963 upstream.

    If the current configuration supports 2 to 1 ODM policy, let's also
    enable the windowed MPO feature.
