Here the same. Each change to the binding should be explained (answer

Apologies for the late reply, the driver doesn't have compatible with 
"microchip,sam9x60-can",
so I made "atmel,at91sam9x5-can" as fallback driver

Sure, I will include the reason for changes in commit message for the

I think a better answer is:

The CAN IP core on the microchip,sam9x60-can is compatible with the IP
core on the "atmel,at91sam9x5-can".

Any changes to the binding must be clearly expressed in the commit msg,
with appropriate reasoning.
