Sorry, not sure I understand clearly here.

This the dts file ie used matched compatible.
compatible = "engicam,icore-mx8mm-ctouch2", "engicam,icore-mx8mm",
                     "fsl,imx8mm";

I did build the dtbs_check without showing any issues like,

$ make ARCH=arm64 dtbs_check
...

    From schema: /w/dt-schema/dt-schema/dtschema/schemas/property-units.yaml
  DTC     arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2.dtb
  DTC     arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2-of10.dtb
  DTC     arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-edimm2.2.dtb
..

Can you let me know what I missed here?

Jagan.
