[PATCH net-next v4 0/7] MT7530 DSA Subdriver Improvements Act II

[Arınç ÜNAL via B4 Relay]

Hello!

This is the second patch series with the goal of simplifying the MT7530 DSA
subdriver and improving 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:

rgmii-only-gmac0-mt7621-unielec-u7621-06-16m.dtb
gmac0-and-gmac1-mt7621-unielec-u7621-06-16m.dtb

MT7622 Bananapi, MT7531:

gmac0-and-gmac1-mt7622-bananapi-bpi-r64.dtb

tftpboot 0x40000000 arm64-Image; tftpboot 0x45000000 arm64-rootfs.cpio.uboot; tftpboot 0x4a000000 $dtb; booti 0x40000000 0x45000000 0x4a000000

MT7623 Bananapi, standalone MT7530:

rgmii-only-gmac0-mt7623n-bananapi-bpi-r2.dtb
gmac0-and-gmac1-mt7623n-bananapi-bpi-r2.dtb

tftpboot 0x80008000 arm-zImage; tftpboot 0x83000000 arm-rootfs.cpio.uboot; tftpboot 0x83f00000 $dtb; bootz 0x80008000 0x83000000 0x83f00000
