drivers: can: unify spelling of CAN Flexible Data-rate abbreviation Unify spelling of CAN Flexible Data-rate abbreviation to "CAN FD" instead of "CAN-FD". The former aligns with the CAN in Automation (CiA) recommendation. Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>

description: Specialization of Bosch m_can CAN FD controller for Atmel SAM0
sam: can: CAN driver for SAM0 socs Driver was based on can_sam. SAMC21 has only 1 interrupt for one can "output", so can interrupt has to executes two lines of interrupts. CAN is configured to use OSC48M clock via GLCK7. GLCK7 is set by divider configured from dts. Signed-off-by: Kamil Serwus <kserwus@gmail.com>

drivers: can: mcan: use per-instance message RAM configuration Restructure the Bosch M_CAN driver backend to use per-instance Message RAM configuration. This removes the need for a common, artificial "can" devicetree node for SoCs with multiple Bosch M_CAN-based CAN controllers and allows for per-instance configuration of the number of e.g. standard (11-bit) and extended (29-bit) filter elements. As part of the restructure, software handling of CAN filter flags was moved from per-flags bitfields to per-filter bitfields, solving an issue when using more than 32 standard (11-bit) filter elements or more than 16 extended (29-bit) filter elements.
