The previous API can't change the sampling-point and only allowed bitrates that fit the time segments. The new API allows for shifting the sampling-point and adjusts the number of time quantum in a bit to all more possible bitrates. The functions to calculate the timings are moved to the can_common file. They can be used for all drivers. Signed-off-by: Alexander Wachter <alexander@wachter.cloud>
