The plan is: 4.21: allow using both modes, add the "amlogic,canvas" property to the dts files 4.22: remove the old way and change the amlogic,canvas property to mandatory This should allow for a nice transition.

The meson DRM driver currently uses constant, static canvas indexes. This is not optimal and could conflict with other drivers also using canvases. This patch series allows the driver to optionnally use a canvas provider module that is able to dispatch canvases, on demand and free of conflict. In the future, the current way of doing things will be deprecated.
