Idea is to move common nodes in separate dtsi instead of adding redundant nodes into respective areas. let me know if it still confusing. Jagan.

A file which *only* includes another file does not fulfill this idea of moving common nodes to a separate DTSI file. Or if I still miss something, please point me, what common nodes are stored in imx8mm-engicam-edimm2.2.dtsi? Best regards, Krzysztof

Yes, imx8mm-engicam-edimm2.2.dtsi is empty now but nodes like PCIe, CSI, DSI will support once the respective drivers are part of Mainline but those are not supported in C.TOUCH2 carrier board dtsi. There are some GPIO pins differences between EDIMM2.2 and C.TOUCH2 carriers on WiFi/BT so those will be part of the respective carrier dtsi. Hope this would clear. Jagan.

Don't create empty files. Once you decide to bring new features, you create a new file. Best regards, Krzysztof
