Series [v5,01/13] fbdev: Add Kconfig options to select different fb_ops helpers | expand

Commit Message

Thomas Zimmermann May 30, 2023, 3:02 p.m. UTC 
Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Armada 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.

v4:
	* use initializer macros for struct fb_ops
v2:
	* use FB_IO_HELPERS option
