I have a BayTrail board with two HDMI ports and running the default Tizen 3.0M1 release.  The first HDMI shows up just fine but I can't get the second screen to display anything.  I tried enabling the second screen through the kernel command line parameters (video=HDMI-1:e video=HDMI-2:e) and running xrandr.  This is my output from xrandr -q

Screen 0: minimum 320 x 200, current 640 x 480, maximum 8192 x 8192
VGA1 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0  
   800x600        60.3     56.2  
   848x480        60.0  
   640x480        59.9* 
HDMI1 connected 640x480+0+0 (normal left inverted right x axis y axis) 256mm x 144mm
   1920x1080      60.0 +   60.0     50.0     59.9     40.0  
   1920x1080i     60.1     50.0     60.0  
   1280x720       60.0     50.0     59.9  
   1440x576i      50.1  
   1440x480i      60.1     60.1  
   720x576        50.0  
   720x480        60.0     59.9  
   640x480        60.0     59.9* 
DP1 disconnected (normal left inverted right x axis y axis)

Is there some other configuration I need?  I tried this on both X and Wayland.  Seems more like a DRM issue at this point.
