Subject: [PATCH net-next 0/8] net: ethernet: ti: am65-cpsw: add multi port support in mac-only mode

Hi

This series adds multi-port support in mac-only mode (multi MAC mode) to TI
AM65x CPSW driver in preparation for enabling support for multi-port devices,
like Main CPSW0 on K3 J721E SoC or future CPSW3g on K3 AM64x SoC.

The multi MAC mode is implemented by configuring every enabled port in "mac-only"
mode (all ingress packets are sent only to the Host port and egress packets
directed to target Ext. Port) and creating separate net_device for
every enabled Ext. port.

Patches 1-3: Preparation patches to improve K3 CPSW configuration depending on DT
Patches 4-5: Fix VLAN offload for multi MAC mode
Patch 6: Fixes CPTS context lose issue during PM runtime transition
Patches 7-8: add multi-port support to TI AM65x CPSW

Grygorii Strashko (8):
  net: ethernet: ti: am65-cpsw: move ale selection in pdata
  net: ethernet: ti: am65-cpsw: move free desc queue mode selection in pdata
  net: ethernet: ti: am65-cpsw: use cppi5_desc_is_tdcm()
  net: ethernet: ti: cpsw_ale: add cpsw_ale_vlan_del_modify()
  net: ethernet: ti: am65-cpsw: fix vlan offload for multi mac mode
  net: ethernet: ti: am65-cpsw: keep active if cpts enabled
  net: ethernet: ti: am65-cpsw: prepare xmit/rx path for multi-port
    devices in mac-only mode
  net: ethernet: ti: am65-cpsw: add multi port support in mac-only mode
