What is the kernel branch "toradex_4.1-2.0.x-imx" for?

I’m using it successfully with a colibri imx6dl because the “toradex_imx_4.1.15_1.0.0_ga” branch doesn’t seem to have the dts files (at least, I don’t see them).

The toradex_4.1-2.0.x-imx branch is the latest 4.1 kernel used for our i.MX6 & i.MX7 modules beginning with our 2.7 Linux images.

Prior to 2.7, i.MX6 used the 3.14.52 kernel and only i.MX7 used the toradex_imx_4.1.15_1.0.0_ga branch.

The naming of the branches follows that of the official NXP branch names from which they were forked.

BTW: This would all be explained here.
