[PATCH net-next v3 0/7] MT7530 DSA Subdriver Improvements Act I

[Arınç ÜNAL via B4 Relay]

Hello!

This patch series simplifies the MT7530 DSA subdriver and improves the
logic of the support for MT7530, MT7531, and the switch on the MT7988 SoC.

I have done a simple ping test to confirm basic communication on all switch
ports on MCM and standalone MT7530, and MT7531 switch with this patch
series applied.

MT7621 Unielec, MCM MT7530:

MT7622 Bananapi, MT7531:

MT7623 Bananapi, standalone MT7530:
