I need to use can bus for my application. The chip that will be used will be the MCP2515 can bus ic. For testing puposes i went and tried the CAN sample which is meant for the NRF51 if im right. Futher i looked into other people trying this but i cant seem to get it the point where i get errors that are fixable for me. I have added an overlay (used a copy from RE: nRF9160 samples : undefined device names for device_get_binding )
I constantly get problems of macros missing as shown below:

The only thing that i was able to find that it has something to do with the devicetree. But i dont understand why the headers are missing in the sample code.
Any help is much appriciated.
