[PATCH v2 6/8] drm/mipi-dbi: Support shadow-plane state

[Noralf Trønnes]

Den 02.12.2022 13.56, skrev Thomas Zimmermann:
> Implement MIPI DBI planes with struct drm_shadow_plane_state, so that the
> respective drivers can use the vmap'ed GEM-buffer memory. Implement state
> helpers, the {begin,end}_fb_access helpers and wire up everything.
> 
> With this commit, MIPI DBI drivers can access the GEM object's memory
> that is provided by shadow-plane state. The actual changes to drivers
> are implemented separately.

> v2:
> 	* use shadow-plane state directly (Noralf)
