Let's make it obvious:

$ make -j4 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/arm/fsl.yaml

make[1]: Entering directory '/home/dev/linux/linux/out'
UPD include/config/kernel.release
DTC arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2.dtb
DTC arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2.dt.yaml
CHECK arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2.dt.yaml
/home/dev/linux/linux/out/arch/arm64/boot/dts/freescale/imx8mm-icore-mx8mm-ctouch2.dt.yaml: /: compatible: 'oneOf' conditional failed, one must be fixed:
['engicam,icore-mx8mm-ctouch2', 'engicam,icore-mx8mm', 'fsl,imx8mm'] is too long
Additional items are not allowed ('fsl,imx8mm' was unexpected)
