While R-Car V4H supports 8 CAN-FD channels, and White-Hawk has transceivers mounted for the first 4 channels, my test results are similar to what Ulrich Hecht reported for R-Car V3U on the Falcon development board before, i.e. only channels 0 and 1 work, and thus this series enables support for these channels only. Whether this is a CAN-FD driver issue, a pin control issue, an IP core issue, or an SoC integration issue is still to be seen... For testing, this series and its dependencies can be found at [1]. Thanks for your comments!
