Thus, add their respective transceivers 1 and 2 dt nodes to add support for these CAN instances. CAN instance 3 in the main domain is brought on the common processor board through header J27. The CAN High and Low lines from the SoC are routed through a mux on the SoM. The select lines need to be set for the CAN signals to get connected to the transceiver 3 on the common processor board. Therefore, add transceiver dt nodes to add support for this CAN instance.
