From: Franklin S Cooper Jr <redacted> Add documentation to describe usage of the new can-transceiver binding. This new binding is applicable for any CAN device therefore it exists as its own document.

Typically these limitations are static and the transceivers themselves +provide no way to detect this limitation at runtime. For this situation, +the "can-transceiver" node can be used. + +Required Properties: + max-bitrate: a positive non 0 value that determines the max + speed that CAN/CAN-FD can run.
