Hello, This patch series fixes support for planes that cross the screen boundaries. The KMS API supports such a configuration, but the DU and VSP hardware doesn't. This leads to different kind of dispay artifacts or hangs. The series starts with a bit of refactoring to share existing code and make it easier to share new code (1/3). Patch 2/3 then reject planes that are fully off-screen as they don't work properly and we have currently no use case for them. Finally, patch 3/3 clips planes to screen boundaries to fix the main issue. The patches are based on top of Dave's latest master branch.
