Hi all,
This patch series enables support for the CAN-FD interface on the Renesas
R-Car V4H (R8A779G0) SoC, and for the first two CAN-FD channels on the
Renesas White-Hawk development board.
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!
