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.

This series does not affect on existing CPSW2g one Ext. Port devices and xmit
path changes are done only for multi-port devices by splitting xmit path for
one-port and multi-port devices. 

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
Patch 7: Fixes TX csum offload for multi MAC mode
Patches 8-9: add multi-port support to TI AM65x CPSW

changes in v2:
- patch 8: xmit path split for one-port and multi-port devices to avoid
  performance losses 
- patch 9: fixed the case when Port 1 is disabled
- Patch 7: added fix for TX csum offload 

v1: https://lore.kernel.org/patchwork/cover/1315766/
