[PATCH v5 22/32] drm/msm/dpu: rework dpu_plane_sspp_atomic_update()

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

 



Split pipe-dependent code from dpu_plane_sspp_atomic_update() into the
separate function dpu_plane_sspp_update_pipe(). This is one of
preparational steps to add r_pipe support.
