Doesn't match your dts file. Plus looks like a lot of redundancy.

Run dtbs_checks and with W=1 and make sure you aren't adding more 
warnings. Lots will be from the base SoC dtsi, but feel free to fix some 
of those too.

Name imx6ul-var-dart-common.dtsi should be okay, as the file includes
imx6ul.dtsi?
