CANFD block on RZ/G2L SoC is almost identical to one found on R-Car Gen3 SoC's. On RZ/G2L SoC interrupt sources for each channel are split into individual sources. Cheers, Prabhakar Changes for v4: * Included RB tag from Rob for DT binding patch. * Split up the global IRQ handlers so that the code is re-used by both RZ/G2L and R-Car Gen3 SoC's as suggested by Geert. Changes for v3: * Dropped core clock addition patches from this series (its queued up already in renesas-clk-for-v5.15) * Added reset-names in binding doc as suggested by Philipp * Updated interrupt names in binding doc as suggested by Geert * Updated the driver to handle the above DT binding changes Changes for v2: * Added interrupt-names property and marked it as required for RZ/G2L family * Added descriptions for reset property * Re-used irq handlers on RZ/G2L SoC * Added new enum for chip_id * Dropped R9A07G044_LAST_CORE_CLK * Dropped patch (clk: renesas: r9a07g044-cpg: Add clock and reset entries for CANFD) as its been merged into renesas tree v1: https://patchwork.kernel.org/project/linux-renesas-soc/ cover/20210715182123.23372-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ Lad Prabhakar (3): dt-bindings: net: can: renesas,rcar-canfd: Document RZ/G2L SoC can: rcar_canfd: Add support for RZ/G2L family arm64: dts: renesas: r9a07g044: Add CANFD node .../bindings/net/can/renesas,rcar-canfd.yaml | 69 +++- arch/arm64/boot/dts/renesas/r9a07g044.dtsi | 41 +++ drivers/net/can/rcar/rcar_canfd.c | 338 ++++++++++++++---- 3 files changed, 369 insertions(+), 79 deletions(-)
