Merge patch series "can: rcar_canfd: Add support for R-Car V4H systems"
Geert Uytterhoeven <geert+renesas@glider.be> says: This patch series adds support for the CAN-FD interface on the Renesas R-Car V4H (R8A779G0) SoC and support for CAN transceivers described as PHYs to the R-Car CAN-FD driver. It includes several fixes for issues (some minor) detected while adding the support and during testing. More details can be found in the individual patches. This has been tested on the Renesas White-Hawk development board using cansend, candump, and canfdtest: - Channel 0 uses an NXP TJR1443AT CAN transceiver, and works fine, - Channels 1-7 use Microchip MCP2558FD-H/SN CAN transceivers (not mounted for channels 4-7), which do not need explicit description. While channel 1 works fine, channels 2-3 do not seem to work. Hence despite the new fixes, the 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 (FTR, [2] does not help). 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...
