Subject: [RFC PATCH net-next 0/12] net: dsa: mt7530: fix port 5 phylink, phy muxing, and port 6
Hello!
This patch series is mainly focused on improving the support for port 5,
setting up port 6, and refactoring the MT7530 DSA subdriver.
The only missing piece to properly support port 5 as a CPU port is the
fixes [0] [1] [2] from Richard.
I have very thoroughly tested the patch series with every possible mode to
use. I'll let the name of the dtb files speak for themselves.

Current CPU ports setup of MT7530:
mt7530_setup()
-> mt7530_setup_port5()
mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt7530_mac_config()
-> mt7530_setup_port5()
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup() sets up port 6, rename to mt7530_setup_port6()
How it will be with the patch series:
mt7530_setup()
-> mt7530_setup_port5() runs if the port is not used as a CPU, DSA, or user port
mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt7530_mac_config()
-> mt7530_setup_port5()
-> mt7530_setup_port6()
CPU ports setup of MT7531 for reference:
mt7531_setup()
-> mt753x_cpu_port_enable()
-> mt7531_cpu_port_config()
-> mt7531_mac_config()
-> mt7531_rgmii_setup()
-> mt7531_sgmii_setup_mode_an()
-> etc.
mt753x_phylink_mac_config()
-> mt753x_mac_config()
-> mt7531_mac_config()
-> mt7531_rgmii_setup()
-> mt7531_sgmii_setup_mode_an()
-> etc.
