How to add New Haven NHD-7.0-800480EF-ATXL#-CTP display to i-MX6 for Linux?

I want to add this New haven & inch LCD to our board which is running Linux but I am unable to modify the device tree file for the this display.This Display has RGB parallel Interface.

The model you mention should use the EDT Focaltech FT5x06 controller I believe. The driver is here. Note however that the driver in the 3.14.52 kernel which we use for iMX6 does not have device tree support. It would require backporting from a more recent kernel like here.

A device tree binding can then be used similar to here.

Thanks for Replay.
When I check the boot logs for kernel I am getting the Below error regarding backlight.

backlight_lcd.18 supply power not found, using dummy regulator

Can you share the exact Linux image version on the module? The output of the following would be helpful.

uname -a
cat /etc/issue

Now I am getting The Lcd Backlight On but its showing blurr (showing lining on screen).I want to see the kernel prompt on the display .How should I move forward to get the kernel login prompt on display?
Please suggest the modifications need to be done in .dtsi and drivers or rootfs.
