Subject[PATCH v6 5/6] dt-bindings: can: m_can: Document new can transceiver binding
Date
From: Franklin S Cooper Jr <fcooper@ti.com>

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.
