[PATCH 41/43] drm/tiny/st7735r: Use fbdev-dma

From: Thomas Zimmermann <tzimmermann@suse.de>
Date: 2024-03-12 15:50:15
Also in: dri-devel
Subsystem: drm drivers, drm drivers and misc gpu patches, the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Linus Torvalds

Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports
damage handling, which is required by st7735r. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.
