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

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

tftpboot 0x80008000 mips-uzImage.bin; tftpboot 0x83000000 mips-rootfs.cpio.uboot; tftpboot 0x83f00000 $dtb; bootm 0x80008000 0x83000000 0x83f00000

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

This patch series is the continuation of the patch series linked below.
