a question about device tree files

Dear Sir

many sorry to take up your valuable time.

- I have an EDM1 (wandboard) + a hardware extension for LVDS panel - I am using Fedora 21 + Linux kernel 3.19, mainline kernel - LVDS panel is HannStar, HSD100pxn1

I am trying to change dts files related to imx6 to drive LVDS panel and I managed to create a flash on the screen right after booting up.

But the screen is dark and off. I do not see the desktop on it. What files i should change in arch/arm/boot/dts/ to get the screen work?

is there any free Linux kernel for driving LVDS panel attached to the wandboard?

Any comments will be much appreciated

Regards
