The transceiver is an analog device that needs to support faster
switching frequency (FETs) including minimizing delay to support CAN-FD
ie higher bitrate. From the transceiver perspective the bits for

I think you are mixing up ISO layer 1 and ISO layer 2.
In order to provide higher data throughput without putting extra limits
on transceiver & wire, the requirement fo

So while _a_ transceiver may be spec'd to 1MBit during arbitration,
CAN FD packets may IMHO exceed that speed during data phase.
When the bitrate is limited to 1Mbit/s you are ONLY allowed to use
1Mbit/s in the data section too (either with CAN or

Add documentation to describe usage of the new fixed transceiver binding.
This new binding is applicable for any CAN device therefore it exists as
its own document.
