This series fixes two issues we found with the setup of the CAN controller of Intel Elkhart Lake CPUs:
- Patch 1 fixes an incorrect reference clock rate, which caused the configured and the actual bitrate always to differ by a factor of 2. - Patches 2-4 fix a deviation between the driver and the documentation. We did not actually see issues without these patches, however we did only superficial testing and may just not have hit the specific bittiming values that violate the documented limits.
Matthias Schiffer (4): can: m_can: pci: fix incorrect reference clock rate Revert "can: m_can: remove support for custom bit timing" can: m_can: make custom bittiming fields const can: m_can: pci: use custom bit timings for Elkhart Lake
