I can't speak for the other two .dtsi files but both kontron .dtsi files
are used by barebox:
- https://elixir.bootlin.com/barebox/v2025.11.0/source/arch/arm/dts/imx6dl-samx6i.dts#L8
- https://elixir.bootlin.com/barebox/v2025.11.0/source/arch/arm/dts/imx6q-samx6i.dts#L8
Removing them here will cause a regression for barebox.
Regards,
Marco
