    Subject[PATCH 5.15 251/667] drm/msm/dpu: adjust display_v_end for eDP and DP
    Date
    From: Kuogee Hsieh <quic_khsieh@quicinc.com>

    [ Upstream commit e18aeea7f5efb9508722c8c7fd4d32e6f8cdfe50 ]

    The “DP timing” requires the active region to be defined in the
    bottom-right corner of the frame dimensions which is different
    with DSI. Therefore both display_h_end and display_v_end need
    to be adjusted accordingly. However current implementation has
    only display_h_end adjusted.
