Subject: [PATCH v3 net-next 00/11] Add WED support for MT7986 chipset

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 v2:
- fix build warnings in patch 9/11

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
