According to Atmel's guideline...
http://www.at91.com/linux4sam/bin/view/Linux4SAM/UsingAtmelDRMDriver
the "fbdev emulation mode" could be set from kernel command line (LVDS-1:...)
however, driver register it as DRM_MODE_CONNECTOR_Unknown connector.
Actually we using sama5d3x with LVDS cable so that below patch would be correct.
But I don't know the other case such as HDMI, composite...
Do we need to consider using DT or auto-detection??
