The stage contains configuration for a mixer pair. Currently the plane supports just one stage and 2 pipes. Quad-pipe support will require handling 2 stages and 4 pipes at the same time. In preparation for that add a separate define, PIPES_PER_PLANE, to denote number of pipes that can be used by the plane. With that being used as a commit message: Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> Please use this as an example of what is expected from the commit messages. -- With best wishes Dmitry
