NAME
       struct_drm_fb_helper_funcs - driver callbacks for the fbdev emulation library

SYNOPSIS
       struct drm_fb_helper_funcs {
	 void (* gamma_set) (struct drm_crtc *crtc, u16 red, u16 green,u16 blue, int regno);
	 void (* gamma_get) (struct drm_crtc *crtc, u16 *red, u16 *green,u16 *blue, int regno);
	 int (* fb_probe) (struct drm_fb_helper *helper,struct drm_fb_helper_surface_size *sizes);
	 bool (* initial_config) (struct drm_fb_helper *fb_helper,struct drm_fb_helper_crtc **crtcs,struct drm_display_mode **modes,bool *enabled, int width, int height);
       };

MEMBERS
       gamma_set
	   Set the given gamma lut register on the given crtc.

       gamma_get
	   Read the given gamma lut register on the given crtc, used to save the current lut when force-restoring the fbdev for e.g. kdbg.

       fb_probe
	   Driver callback to allocate and initialize the fbdev info structure. Futhermore it also needs to allocate the drm framebuffer used to
	   back the fbdev.

       initial_config
	   Setup an initial fbdev display configuration

DESCRIPTION
       Driver callbacks used by the fbdev emulation helper library.
