Re: [PATCH] drm/msm/mdp5:Add DMA pipe planes for MDP5

Hi Rob, DMA pipes can be configured to work in either line mode or block mode. In line mode, it is the same as RGB/VIG pipes except no CSC/SCALE/PP/... support. So it can be used by any CRTC. In block mode, it is used as a rotator with writeback(0/1) interface which is not covered by this change.
