[PATCH v8 1/4] drm/msm/dpu: adjust display_v_end for eDP and DP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
