[PATCH v3 09/15] drm/msm/dpu: split PIPES_PER_STAGE definition per plane and mixer

From: Jun Nie
Date: Thu Dec 19 2024 - 02:52:18 EST


Split PIPES_PER_STAGE definition per plane and mixer pair. Because
there are more than 2 pipes in quad pipe case, while 2 pipes at most
per mixer pair. A stage struct serve a mixer pair, so pipes per
plane is split out as PIPES_PER_PLANE.
