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.

Installation
------------
1. Run tftp server on your PC (IP: 192.168.2.2) and put OpenWrt initramfs
image (initramfs.bin) to the tftp root dir
2. Open the following link in the browser to enable telnet:
http://192.168.2.1/cgi-bin/telnet_ssh
3. Connect to the router (default IP: 192.168.2.1) using telnet shell
(credentials - user:admin)
4. Run the following commands in the telnet shell (this will install
OpenWrt initramfs image on nand flash):
cd /tmp
tftp -g -r initramfs.bin 192.168.2.2
mtd write initramfs.bin firmware
mtd erase firmware_backup
reboot
5. Copy OpenWrt sysupgrade image (sysupgrade.bin) to the /tmp dir of the
router
6. Connect to the router (IP: 192.168.1.1) using ssh shell and run
sysupgrade command:
sysupgrade -n /tmp/sysupgrade.bin
Return to stock
---------------
1. Copy stock firmware (stock.bin) to the /tmp dir of the router using scp
2. Run following command in the router shell:
cd /tmp
mtd write stock.bin firmware
reboot
Recovery
--------
Connect uart (pins are silkscreened on the pcb), interrupt boot process by
pressing any key, use u-boot menu to flash stock firmware image or OpenWrt
initramfs image.
