Not related to this patch: do you plan to submit ts4600.dts for
mainline inclusion as well?

It's in my todo list yes, but nothing really planned currently, do you
think i should keep the mx28evk dtb instead?

I am not familar with this board. Do you mean that you use
imx28-evk.dtb to boot it?

IMHO it would be nice to have a dedicated ts4600.dts to avoid confusion.

Yes currently i'm using the mainstream Linux kernel using the mx28evk
defconfig and its Device Tree.
Obviously not all peripherals are working.

For my understanding, are we talking about adding the dts in U-Boot or
in Linux?

Ok, got it. So that means that having a dedicated ts4600.dts file in
mainline kernel would be helpful.

I am talking about adding ts4600.dts file to mainline kernel.
