CAN instances 3 and 5 in the main domain are brought on the common
processor board through header J27 and J28. 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 transceivers on
the common processor board. Threfore, add respective mux, transceiver
dt nodes to add support for these CAN instances.

You will get more warning with @0 and @1
