My intention wasn't to point to the barebox-only
"barebox,disable-deep-probe" property. I was refering to the include
line.

The two .dtsi files we're talking about are SoM .dtsi files. We don't
have access to the Kontron EVK baseboard which uses this SoM.

I've added a few Kontron devs which may can add the missing baseboard
support.

I could also add the imx6dl-samx6i.dts and imx6q-samx6i.dts like we do
in barebox. But as said, this would be a devicetree for a SoM which
makes sense for the bootloader but not for the kernel.

  Marco
