Hi Wu Mr,

Yes, you can. In our default BSP it support the LVDS dual display and need to set right display mode  ldb=spl0 parameters in u-boot.

There are boolean properties (see ldb.c):

dual-mode

split-mode

default should separate mode.

See also the new "display-timings" entries in the device tree, they allow to assign a display to a lvds port, setting proper display options.

The the ldb binding guide for device tree you can refer to.

Documentation/devicetree/bindings/video/fsl,ldb.txt

Firstly you need to confirm your harware desing work well, and then do porting the lvds screen.

Hope this can do help for you.
Have a great day,
Rita
