hi,

i am having two encoders dsi1 and dsi2 of same resolution, i want to
configure as single resolution 960x864,

after configuring as right-of , i got 960x864 resolution, but not able to
use as single fb as of xinerma
xrandr --output DSI-1 --mode 480x864 --right-of DSI-2

root at linaro-alip:~# xrandr
Screen 0: minimum 320 x 200, current 960 x 864, maximum 2048 x 2048
DSI-1 connected 480x864+480+0 (normal left inverted right x axis y axis)
0mm x 0mm
   480x864       60.00*
DSI-2 connected 480x864+0+0 (normal left inverted right x axis y axis) 0mm
x 0mm
   480x864       60.00*

any suggestions on how to configure it as xinerma? if not possible i guess
need to modify the drm fbdev and divide the buffer(h/2) to left and right
encoders.
