Hi, Eric/Jesse
    How about this patch set?
    On the boxes based on G4X platform there is no HDMI/DP output port.
But the HDMI/DP output port will be initialized. In such case the xrandr
will report too many output devices whose status is disconnected.  Some
users will be confusing.
    How about using the child device parsed from VBT to decide whether
the given HDMI/DP should be initialized?
   
Any comments are appreciated.

Thanks.
