On this board, clocks, power-domains, and resets must be accessed only through SCMI firmware. Just like its GPIO[1] and PWM[2] counterparts, this series is a bit special, in that several patches are not meant to be applied upstream yet: 1. The first RFC patch documents support for CAN-FD on R-Car X5H, 2. Patches 2-4, targeting the can tree, add driver support for CAN-FD on R-Car X5H, 3. Patch 5, targeting a shared DT bindings branch, adds a CAN-FD clock definition, 4. RFC patch 6 adds CAN-FD device nodes to the R-Car X5H .dtsi file, 5. The remaining patches are marked DNI, and depend on code or DTS that is not yet upstream. More detail can be found in the individual patches. CAN-FD channels 1 to 6 and 12 to 15 have been tested on Ironhide using canfdtest and an oscilloscope. Thanks for your comments!
