[PATCH v4 3/4] dt-bindings: can: m_can: Document new can transceiver binding

2017-08-09 Thread Franklin S Cooper Jr 
Add information regarding can-transceiver binding. This is especially
important for MCAN since the IP allows CAN FD mode to run significantly
faster than what most transceivers are capable of.

Drop unit address.
Switch from using fixed-transceiver to can-transceiver
Indicate that can-transceiver is an optional subnode not a property.
