This series adds support for the CAN-FD IP core found on the Rockchip
RK3568.
The IP core is a bit complicated and has several documented errata.
The driver is added in several stages, first the base driver including
the RX-path. Then several workarounds for errata and the TX-path, and
finally features like hardware time stamping, loop-back mode and
bus error reporting.

Marc
