Hi!
As per Chapter 6.5.16 of the RZ/N1 Peripheral Manual, The SJA1000 CAN controller does not support Clock Divider Register compared to the reference Philips SJA1000 device.
This patch adds a device quirk to handle this difference.
I don't think this is suitable for stable (at least 5.10.X and older) as we don't have user of the quirk queued up.
Best regards, Pavel
