[PATCH 2/4] can: fixed-transceiver: Add documentation for CAN fixed transceiver bindings
Add documentation to describe usage of the new fixed transceiver binding.
This new binding is applicable for any CAN device therefore it exist as
its own document.

+Fixed transceiver Device Tree binding
+--
+
+CAN transceiver typically limits the max speed in standard CAN and CAN FD
+modes. Typically these limitations are static and the transceivers themselves
+provide no way to detect this limitation at runtime. For this situation,
+the "fixed-transceiver" node can be used.
+
+Properties:
+
+Optional:
+ max-arbitration-speed: a positive value non 0 value that determines the max
+speed CAN can run in non CAN-FD mode or during the
+arbitration phase in CAN-FD mode.
+
+ max-data-speed:a positive value that determines the max data rate
+that can be used in CAN-FD mode. A value of 0
+implies CAN-FD is not supported by the transceiver.
+
+Examples:
+
+Based on Texas Instrument's TCAN1042HGV CAN Transceiver
+
+m_can0 {
+
+ fixed-transceiver@0 {
+ max-arbitration-speed = <100>;
+ max-data-speed = <500>;
+ };
+ ...
+};
