EN7581 mac controller is mainly composed by Frame Engine (FE) and QoS-DMA (QDMA) modules. FE is used for traffic offloading (just basic functionalities are supported now) while QDMA is used for DMA operation and QOS functionalities between mac layer and the dsa switch (hw QoS is not available yet and it will be added in the future). Currently only hw lan features are available, hw wan will be added with subsequent patches. Changes since v6: - set eth->ports[] before registering netdevice - make page_pool_params const Changes since v5: - implement .ndo_get_stats64() callback and remove duplicated ethtool entries - remove "ethernet-controller.yaml#" from parent node in device tree binding - rename child node from "mac" to "ethernet" in device tree binding - fix checkpatch errors Changes since v4: - fix compilation warnings - use airoha_qdma_rr() and not airoha_rr() in airoha_qdma_set_irqmask() - add missing descriptions in dt-binding - remove mdio node in binding example Changes since v3: - rework architecture to allow future gdm{1,4} support - read REG_INT_ENABLE() register in airoha_qdma_set_irqmask() to guarantee airoha_qdma_wr() complete in the spinlock critical section - thx Arnd for the clarification - remove unnecessary wmb() - remove debugfs - move register definitions in .c and remove .h - fix warnings - enable NAPI thread by default Changes since v2: - rename airoha,en7581.yaml in airoha,en7581-eth.yaml - remove reset dependency in airoha,en7581-eth.yaml - remove airoha_dev_change_mtu() callback Changes since v1: - drop patch 2/3 - remove queue lock for rx queues - add bql support - add ethtool stats support - fix possible infinite loop in airoha_qdma_rx_process routine - always destroy page_pool in case of error during initialization - cosmetics Lorenzo Bianconi (2): dt-bindings: net: airoha: Add EN7581 ethernet controller net: airoha: Introduce ethernet support for EN7581 SoC .../bindings/net/airoha,en7581-eth.yaml | 143 + MAINTAINERS | 9 + drivers/net/ethernet/mediatek/Kconfig | 11 +- drivers/net/ethernet/mediatek/Makefile | 1 + drivers/net/ethernet/mediatek/airoha_eth.c | 2768 +++++++++++++++++ 5 files changed, 2931 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/net/airoha,en7581-eth.yaml create mode 100644 drivers/net/ethernet/mediatek/airoha_eth.c
