[v2,39/43] drm/tiny/repaper: Use fbdev-dma

Commit Message

Thomas Zimmermann April 10, 2024, 1:02 p.m. UTC

Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports
damage handling, which is required by repaper. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.
