Subject: [PATCH 0/3] drm/meson: Add support for Overlay and OSD Plane scaling

This serie adds support for :
- Overlay Plane blended with the primary plane, we can describe as "behind"
- Primary Plane up-scaling up to 5x factor to support the OSD plane being
  upscaled from 1920x1080 when the display mode is set as 3840x2160.

These patches depends on the "drm/meson: Allow using optional canvas provider"
patchset from Maxime Jourdan at [1]
