can: rockchip_canfd: add support for CAN-FD IP core found on Rockchip RK3568

This series adds support for the CAN-FD IP core found on the Rockchip RK3568. The IP core is a bit complicated and has several documented errata. The driver is added in several stages, first the base driver including the RX-path. Then several workarounds for errata and the TX-path, and finally features like hardware time stamping, loop-back mode and bus error reporting. regards, Marc Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> --- David Jander (2): arm64: dts: rockchip: add CAN-FD controller nodes to rk3568 arm64: dts: rockchip: mecsbc: add CAN0 and CAN1 interfaces Marc Kleine-Budde (19): dt-bindings: can: rockchip_canfd: add binding for rockchip CAN-FD controller can: rockchip_canfd: add driver for Rockchip CAN-FD controller can: rockchip_canfd: add quirks for errata workarounds can: rockchip_canfd: add quirk for broken CAN-FD support can: rockchip_canfd: add support for rk3568v3 can: rockchip_canfd: add notes about known issues can: rockchip_canfd: rkcanfd_handle_rx_int_one(): implement workaround for erratum 5: check for empty FIFO can: rockchip_canfd: rkcanfd_register_done(): add warning for erratum 5 can: rockchip_canfd: add functions to check if CAN-FD frames are equal can: rockchip_canfd: add TX PATH can: rockchip_canfd: implement workaround for erratum 6 can: rockchip_canfd: implement workaround for erratum 12 can: rockchip_canfd: rkcanfd_get_berr_counter_corrected(): work around broken {RX,TX}ERRORCNT register can: rockchip_canfd: add stats support for errata workarounds can: rockchip_canfd: prepare to use full TX-FIFO depth can: rockchip_canfd: enable full TX-FIFO depth of 2 can: rockchip_canfd: add hardware timestamping support can: rockchip_canfd: add support for CAN_CTRLMODE_LOOPBACK can: rockchip_canfd: add support for CAN_CTRLMODE_BERR_REPORTING .../bindings/net/can/rockchip,canfd.yaml | 76 ++ MAINTAINERS | 8 + arch/arm64/boot/dts/rockchip/rk3568-mecsbc.dts | 14 + arch/arm64/boot/dts/rockchip/rk3568.dtsi | 39 + drivers/net/can/Kconfig | 1 + drivers/net/can/Makefile | 1 + drivers/net/can/rockchip/Kconfig | 9 + drivers/net/can/rockchip/Makefile | 10 + drivers/net/can/rockchip/rockchip_canfd-core.c | 972 +++++++++++++++++++++ drivers/net/can/rockchip/rockchip_canfd-ethtool.c | 73 ++ drivers/net/can/rockchip/rockchip_canfd-rx.c | 299 +++++++ .../net/can/rockchip/rockchip_canfd-timestamp.c | 105 +++ drivers/net/can/rockchip/rockchip_canfd-tx.c | 167 ++++ drivers/net/can/rockchip/rockchip_canfd.h | 551 ++++++++++++ 14 files changed, 2325 insertions(+) --- base-commit: 1722389b0d863056d78287a120a1d6cadb8d4f7b change-id: 20240729-rockchip-canfd-4233c71f0cc6 Best regards,
