Formally TRMs refer CPSW2G NUSS as two-port Gigabit Ethernet Switch subsystem with port 0 being the CPPI DMA host port and port 1 being the external Ethernet port, but for 1 external port device it's just Port 0 <-> ALE <-> Port 1 and it's rather device with HW filtering capabilities then actually switching device. It's expected to have similar devices, but with more external ports. The new Host port 0 Communications Port Programming Interface (CPPI5) is operating by TI AM654x/J721E NAVSS Unified DMA Peripheral Root Complex (UDMA-P) controller [1]. The CPSW2G contains below modules for which existing code is re-used: - MAC SL: cpsw_sl.c - Address Lookup Engine (ALE): cpsw_ale.c, basically compatible with K2 66AK2E/G - Management Data Input/Output interface (MDIO): davinci_mdio.c, fully compatible with TI AM3/4/5 devices Basic features supported by CPSW2G NUSS driver: - VLAN support, 802.1Q compliant, Auto add port VLAN for untagged frames on ingress, Auto VLAN removal on egress and auto pad to minimum frame size. - multicast filtering - promisc mode - TX multiq support in Round Robin or Fixed priority modes - RX checksum offload for non-fragmented IPv4/IPv6 TCP/UDP packets - TX checksum offload support for IPv4/IPv6 TCP/UDP packets (J721E only). Features under development: - Support for IEEE 1588 Clock Synchronization. The CPSW2G NUSS includes new version of Common Platform Time Sync (CPTS) - tc-mqprio: priority level Quality Of Service (QOS) support (802.1p) - tc-cbs: Support for Audio/Video Bridging (P802.1Qav/D6.0) HW shapers - tc-taprio: IEEE 802.1Qbv/D2.2 Enhancements for Scheduled Traffic - frame preemption: IEEE P902.3br/D2.0 Interspersing Express Traffic, 802.1Qbu - extended ALE features: classifier/policers, auto-aging Patches 1-6 are intended for netdev, Patches 7-11 are intended for K3 Platform tree and provided here for testing purposes. Changes in v6: - fixed comments from Rob Herring and added his Reviewed-by. - added Tested-by: Peter Ujfalusi Changes in v5: - renamed files k3-udma-desc-pool.* k3-udma-desc-pool to k3-cppi-desc-pool.*, and API to k3_cppi_desc_pool_* as requested by Peter Ujfalusi - fixed copy-paste err in am65_cpsw_nuss_ndo_slave_set_rx_mode() which blocked recieving of mcast frames. - added Tested-by: Murali Karicheri Changes in v4: - fixed minor comments from Jakub Kicinski - dependencies resolved: required phy-rmii-sel changes [2] queued for merge except one [3] which is included in this series with Kishon's ask. Changes in v3: - add ARM64 defconfig changes for testing purposes - fixed DT yaml definition - fixed comments from Jakub Kicinski Changes in v2: - fixed DT yaml definition - fixed comments from David Miller v5: https://patchwork.ozlabs.org/cover/1258295/ v4: https://patchwork.ozlabs.org/cover/1256092/ v3: https://patchwork.ozlabs.org/cover/1254568/ v2: https://patchwork.ozlabs.org/cover/1250674/ v1: https://lwn.net/Articles/813087/ TRMs: AM654: http://www.ti.com/lit/ug/spruid7e/spruid7e.pdf J721E: http://www.ti.com/lit/ug/spruil1a/spruil1a.pdf Preliminary documentation can be found at: http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/K3_CPSW2g.html [1] https://lwn.net/Articles/808030/ [2] https://lkml.org/lkml/2020/2/22/100 [3] https://lkml.org/lkml/2020/3/3/724 Grygorii Strashko (11): phy: ti: gmii-sel: simplify config dependencies between net drivers and gmii phy net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled net: ethernet: ti: ale: add support for mac-only mode net: ethernet: ti: ale: am65: add support for default thread cfg dt-binding: ti: am65x: document mcu cpsw nuss net: ethernet: ti: introduce am65x/j721e gigabit eth subsystem driver arm64: dts: ti: k3-am65-mcu: add cpsw nuss node arm64: dts: k3-am654-base-board: add mcu cpsw nuss pinmux and phy defs arm64: dts: ti: k3-j721e-mcu: add mcu cpsw nuss node arm64: dts: ti: k3-j721e-common-proc-board: add mcu cpsw nuss pinmux and phy defs arm64: defconfig: ti: k3: enable dma and networking .../bindings/net/ti,k3-am654-cpsw-nuss.yaml | 225 ++ arch/arm64/boot/dts/ti/k3-am65-mcu.dtsi | 49 + arch/arm64/boot/dts/ti/k3-am65.dtsi | 1 + .../arm64/boot/dts/ti/k3-am654-base-board.dts | 42 + .../dts/ti/k3-j721e-common-proc-board.dts | 43 + .../boot/dts/ti/k3-j721e-mcu-wakeup.dtsi | 49 + arch/arm64/boot/dts/ti/k3-j721e.dtsi | 1 + arch/arm64/configs/defconfig | 3 + drivers/net/ethernet/ti/Kconfig | 20 +- drivers/net/ethernet/ti/Makefile | 3 + drivers/net/ethernet/ti/am65-cpsw-ethtool.c | 747 +++++++ drivers/net/ethernet/ti/am65-cpsw-nuss.c | 1965 +++++++++++++++++ drivers/net/ethernet/ti/am65-cpsw-nuss.h | 142 ++ drivers/net/ethernet/ti/cpsw_ale.c | 38 + drivers/net/ethernet/ti/cpsw_ale.h | 4 + drivers/net/ethernet/ti/k3-cppi-desc-pool.c | 126 ++ drivers/net/ethernet/ti/k3-cppi-desc-pool.h | 30 + drivers/phy/ti/Kconfig | 3 - 18 files changed, 3486 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/ti,k3-am654-cpsw-nuss.yaml create mode 100644 drivers/net/ethernet/ti/am65-cpsw-ethtool.c create mode 100644 drivers/net/ethernet/ti/am65-cpsw-nuss.c create mode 100644 drivers/net/ethernet/ti/am65-cpsw-nuss.h create mode 100644 drivers/net/ethernet/ti/k3-cppi-desc-pool.c create mode 100644 drivers/net/ethernet/ti/k3-cppi-desc-pool.h
