[PATCH 6/7] drm/msm/dpu: switch dpu_encoder to use atomic_mode_set

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

 



Make dpu_encoder use atomic_mode_set to receive connector and CRTC
states as arguments rather than finding connector and CRTC by manually
looping through the respective lists.
