>> In this patch, it moves common dts between imx6ul* and imx6ull* as new
>> files named imx6u*, and the specific part for imx6ul and imx6ull are
>> individual file.
>
>No.  That only helps churn the tree and git history.  Please keep using imx6ul.dtsi and
>simply have it be included by imx6ull.dtsi.
