When fixing the CAN clock frequency, fb12797ab1fe ("can: kvaser_usb: get CAN clock frequency from device"), I introduced a regression.
For Leaf devices based on M32C, the firmware expects bittiming parameters calculated for 16MHz clock. Regardless of the actual clock frequency.
This regression affects M32C based Leaf devices with non-16MHz clock.
Also correct the bittiming constants in kvaser_usb_leaf.c, where the limits are different depending on which firmware/device being used.
Once merged to mainline, I'll backport these fixes for the stable kernels.
Added to linux-can/testing. I had to move the kvaser_usb_driver_info into kvaser_usb_core.c and the keep struct can_bittiming_const kvaser_usb_flexc_bittiming_const in kvaser_usb_hydra.c as structs in header files cause defined but not used warnings on some platforms.
