Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide
direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO
bus the switch listens on. The PHY muxing feature makes use of this.
This is problematic as the PHY may be attached before the switch is
initialised, in which case, the PHY will fail to be attached.
Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration
of switch MDIO bus") on mainline Linux, we can describe the switch PHYs on
the MDIO bus of the switch on the device tree.
When the PHY is described this way, the switch will be initialised first,
then the switch MDIO bus will be registered. Only after these steps, the
PHY will be attached.
Describe the switch PHYs on mt7621.dtsi and remove defining the switch PHY
on the SoC's mdio bus node. When the PHY muxing is in use, the interrupts
for the muxed PHY won't work, therefore delete the "interrupts" property on
the devices where the PHY muxing feature is in use.

Zbtlink ZBT-WG1608 is a Wi-Fi router intendent to use with WWAN (4G/5G)
modems.
Specifications:
* SoC: MediaTek MT7621A
* RAM: 256/512 MiB
* Flash: 16/32 MiB (SPI NOR)
* Wi-Fi:
* MediaTek MT7603E : 2.4Ghz
* MediaTek MT7613BE : 5Ghz
* Ethernet: 10/100/1000 Mbps Ethernet x5 ports (4xLAN + WAN)
* M.2: 1x slot with USB&SIM
* EM7455/EM12-G/EM160R/RM500Q-AE
* USB: 1x 3.0 Type-A port
* External storage: 1x microSD (SDXC) slot
* UART: console (115200 baud)
* LED:
* 1 power indicator
* 1 WLAN 2.4G controlled (wlan 2G)
* 3 SoC controlled (wlan 5G, wwan, internet)
* 5 per Eth phy (4xLAN + WAN)
MAC Addresses:
* LAN : f8:5e:3c:xx:xx:e0 (Factory, 0xe000 (hex))
* WAN : f8:5e:3c:xx:xx:e1 (Factory, 0xe006 (hex))
* 2.4 GHz: f8:5e:3c:xx:xx:de (Factory, 0x0004 (hex))
* 5 GHz : f8:5e:3c:xx:xx:df (Factory, 0x8004 (hex))
Installation:
* Vendor's firmware is OpenWrt (LEDE) based, so the sysupgrade image can
be directly used to install OpenWrt. Firmware must be upgraded using the
'force' and 'do not save configuration' command line options (or
correspondig web interface checkboxes) since the vendor firmware is from
the pre-DSA era.
Recovery Mode:
* Press reset button, power up the device, wait for about 10sec.
* Upload sysupgrade image through the firmware recovery mode web page at
192.168.1.1.

The pins of the MT7530 switch that translate to GPIO 0, 3, 6, 9 and 12 has
got a function, by default, which does the same thing as the netdev
trigger. Because of bridge offloading on DSA, the netdev trigger won't see
the frames between the switch ports whilst the default function will.
Do not use the GPIO function on switch pins on devices that fall under this
category.
Keep it for:
mt7621_belkin_rt1800.dts: There's only one LED which is for the wan
interface and there's no bridge offloading between the "wan" interface and
other interfaces.
mt7621_yuncore_ax820.dts: There's no bridge offloading between the "wan"
and "lan" interfaces.

Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2
pins are available. This achieves 2 Gbps total bandwidth to the CPU using
the second RGMII.
The ports called "wan" are muxed where possible. On a minority of devices,
this is not possible. Those cases:
mt7621_ampedwireless_ally-r1900k.dts: lan3
mt7621_ubnt_edgerouter-x.dts: eth0
mt7621_gnubee_gb-pc1.dts: ethblue
mt7621_linksys_re6500.dts: lan1
mt7621_netgear_wac104.dts: lan4
mt7621_tplink_eap235-wall-v1.dts: lan0
mt7621_tplink_eap615-wall-v1.dts: lan0
mt7621_ubnt_usw-flex.dts: lan1
The "wan" port is just what the vendor designated on the board/plastic
chasis of the device. On a technical level, there is no difference between
a lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Prefer
connecting to WAN via the port described above for these devices to benefit
the feature brought with this patch.
mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it looks
like it should, because the rgmii2 pins are wired to unused components.
Tested on a range of devices documented on the GitHub PR.
