[v2,net-next,00/11] Add WED support for MT7986 chipset

Message

Lorenzo Bianconi Sept. 13, 2022, 5 p.m. UTC

Similar to MT7622, introduce Wireless Ethernet Dispatch (WED) support
for MT7986 chipset in order to offload to the hw packet engine traffic
received from LAN/WAN device to WLAN nic (MT7915E).

Changes since v1:
- drop foe structure in mtk_soc_data structure and fix compilation error
  on ARMv7 (e.g. MT7623)
- add missing dt bindings
- rely on syscon_regmap_lookup_by_phandle to read/write into wed-pcie
  controller

Lorenzo Bianconi (11):
  arm64: dts: mediatek: mt7986: add support for Wireless Ethernet
    Dispatch
  dt-bindings: net: mediatek: add WED binding for MT7986 eth driver
  net: ethernet: mtk_eth_soc: move gdma_to_ppe and ppe_base definitions
    in mtk register map
  net: ethernet: mtk_eth_soc: move ppe table hash offset to mtk_soc_data
    structure
  net: ethernet: mtk_eth_soc: add the capability to run multiple ppe
  net: ethernet: mtk_eth_soc: move wdma_base definitions in mtk register
    map
  net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc
  net: ethernet: mtk_eth_wed: add mtk_wed_configure_irq and
    mtk_wed_dma_{enable/disable}
  net: ethernet: mtk_eth_wed: add wed support for mt7986 chipset
  net: ethernet: mtk_eth_wed: add axi bus support
  net: ethernet: mtk_eth_soc: introduce flow offloading support for
    mt7986
