Subject: [PATCH 29/43] drm/renesas/rz-du: Use fbdev-dma
Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports damage handling, which is required by
rz-du. Avoids the overhead of fbdev-generic's additional shadow buffering. No functional changes.

Thanks a lot.
I just noticed that the drivers under renesas/ don't require damage
handling, so the commit message needs a change.
Best regards
Thomas
Cheers,
Biju
