While the fbdev driver supports panels that may be + * connected to the CLCD internally to the CLCD driver, in DRM the + * panels get split out to drivers/gpu/drm/panels/. This means that, + * in converting from using fbdev to using DRM, you also need to write + * a panel driver (which may be as simple as an entry in + * panel-simple.c). + * + * The driver currently doesn't expose the cursor.
