connector if connected + +The intel x4x and gm45 have very similar integrated graphic devices. +Currently the x4x native graphic init enables VGA, while gm45 can output +on LVDS. + +This patch reuses the x4x graphic initialisation code +to enable output on VGA in gm45 in a way that the behavior is similar to vbios: +If no VGA display is connected the internal LVDS screen is used. +If an external screen is detected on the VGA port it will be used instead. + +Change-Id: I7e9ff793a5384ad8b4220fb1c0d9b28e6cee8391 +Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> +--- +
