I got confirmation the clock to CAN controller is indeed changed from 100
MHz to 200 MHz in release HW & firmware.

I haven't upgraded the FW in a while on our HW so that perhaps explain
why I was seeing expected rate :-)

Can we query the FW version in the driver and set the clock rate
accordingly?

Perhaps or check some clock register. I guess for now it can be 
considered fixed clock since I understood rate was changed before 
released to customers. I.e. customers shouldn't have firmware with 
different rates. At least I hope so :-)
