[PATCH v3 08/15] drm/msm/dpu: handle pipes as array

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

 



Store pipes in array with removing dedicated r_pipe. There are
2 pipes in a drm plane at most currently. While 4 pipes are
needed for new usage case. This change generalize the handling
to pipe pair and ease handling to another pipe pair later.
