Subject: [PATCH net-next v2 0/7] MT7530 DSA Subdriver Improvements Act I

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:

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

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

v2:
- Shorten the patch series, include only 7 patches.
- Add the reviewed-by tags given.
- Patch 1
  - Change variable ordering of mt753x_conduit_state_change().
  - Define the mask variable and store BIT(cpu_dp->index) on it.
  - Disable CPU_EN if priv->active_cpu_ports is 0.
- Patch 5
	- On the patch log, take the irrelevant information about the
    mt7530_setup_port5() call from mt7530_setup() out.
- Patch 6
  - Change the patch log to reflect correct information.

Arınç ÜNAL (7):
