Series drm/fbdev: Remove DRM's helpers for fbdev I/O | expand

Commit Message

Thomas Zimmermann May 15, 2023, 9:40 a.m. UTC 
Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Fbdev-dma does not use damage handling, so DRM's fbdev helpers
are mere wrappers around the fbdev code.

By using fbdev helpers directly within each DRM fbdev emulation,
we can eventually remove DRM's wrapper functions entirely.

v2:
	* use FB_SYS_HELPERS option
