I adding am335x-bone-cc3100-spi.dtsi file which I got from github.com/.../cc3100-spi-kernelmodul. I have modified the file am335x-boneblack.dts to include this new file and tried to build, but getting the following error message. I have also included the am335x-bone-cc3100-spi.dtsi below.

Any idea what could be causing this error message?
