Hi,

I know my response is late ...

I contest the the name too:
1) the can transceiver isn't fixed at all, it limited to the higher
bitrates.

2) of_can_transceiver_is_fixed suggests to test if a transceiver is
fixed, it does not suggest to load some properties from the device tree.
of_can_load_transceiver looks way more clear to me.

That's my opinion.
The important things, like the contents of the functions, look good.

Kind regards,
