I would be happy for suggestion for reference location. Is the next file right location Documentation/networking/device_drivers/can/index.rst for reference to Documentation/networking/device_drivers/can/ctu/ctucanfd-driver.rst It is documentation of the driver for CAN FD open-source IP core developed by the group formed at Czech Technical University. I have probably minor updates for the links to the external resources, AXI, APB and other documentation because it moves from site to site under Intel, ARM, Xilinx web sites hierarchies.
