Subject: drm/tiny/ili9486: Use fbdev-dma
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4f229b50b2de73e8867250226125c35620e2be33;p=users%2Fdwmw2%2Flinux.git

drm/tiny/ili9486: Use fbdev-dma

Implement fbdev emulation with fbdev-dma. Fbdev-dma now supports
damage handling, which is required by ili9486. Avoids the overhead of
fbdev-generic's additional shadow buffering. No functional changes.
