NAME
       drm_fb_helper_initial_config - setup a sane initial connector configuration

SYNOPSIS
       bool drm_fb_helper_initial_config(struct drm_fb_helper * fb_helper, int bpp_sel);

ARGUMENTS
       fb_helper
	   fb_helper device struct

       bpp_sel
	   bpp value to use for the framebuffer configuration

DESCRIPTION
       Scans the CRTCs and connectors and tries to put together an initial setup. At the moment, this is a cloned configuration across all heads
       with a new framebuffer object as the backing store.

       Note that this also registers the fbdev and so allows userspace to call into the driver through the fbdev interfaces.

       This function will call down into the ->fb_probe callback to let the driver allocate and initialize the fbdev info structure and the drm
       framebuffer used to back the fbdev.  drm_fb_helper_fill_var and drm_fb_helper_fill_fix are provided as helpers to setup simple default
       values for the fbdev info structure.

RETURNS
       Zero if everything went ok, nonzero otherwise.
