drm_fb_helper_single_add_all_connectors - add all connectors to fbdev emulation helper
int drm_fb_helper_single_add_all_connectors(struct drm_fb_helper * fb_helper);
fbdev initialized with drm_fb_helper_init
This functions adds all the available connectors for use with the given fb_helper. This is a separate step to allow drivers to freely
assign connectors to the fbdev, e.g. if some are reserved for special purposes or not adequate to be used for the fbcon.
Since this is part of the initial setup before the fbdev is published, no locking is required.

fbdev - video driver for framebuffer device
fbdev is an Xorg driver for framebuffer devices. This is a non-accelerated driver, the following framebuffer depths are supported: 8, 15,
16, 24. All visual types are supported for depth 8, and TrueColor visual is supported for the other depths. Multi-head configurations are
The fbdev driver supports all hardware where a framebuffer driver is available. fbdev uses the os-specific submodule fbdevhw(4) to talk to
the kernel device driver. Currently a fbdevhw module is available for linux.
Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver.
For this driver it is not required to specify modes in the screen section of the config file. The fbdev driver can pick up the currently
used video mode from the framebuffer driver and will use it if there are no video modes configured.
For PCI boards you might have to add a BusID line to the Device section. See above for a sample line. You can use " -scanpci" to figure
out the correct values.
The following driver Options are supported:
Option "fbdev" "string"
The framebuffer device to use. Default: /dev/fb0.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer. Default: on.
Option "Rotate" "string"
Enable rotation of the display. The supported values are "CW" (clockwise, 90 degrees), "UD" (upside down, 180 degrees) and "CCW"
(counter clockwise, 270 degrees). Implies use of the shadow framebuffer layer. Default: off.
