DT 'ethsys' node is being configured as a syscon
to get access to reset and other registers in the
'mediateķ,mt7621-eth' driver. Since the 'sysc' is also
a syscon, provides the clock and also is virtually
mapped from the same physical address 0x1e000000 we
can just use 'sysc' as the phandle for the syscon in
the ethernet node. Compatible string 'mediatek,mt7621-ethsys'
of the node is not being used anywhere inside the kernel
so, this node can be safely removed.

'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller'
and 'MIPS Common Device Memory Map' which are present in some MIPS related
boards. There is already bindings documentation for these two located in:
- Documentation/devicetree/bindings/power/mti,mips-cpc.yaml
- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml
Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

Installation:
Update openWRT firmware using internal GNUBEE uboot:
https://github.com/gnubee-git/GnuBee-MT7621-uboot
By HTTP: Initial uboot address is http://10.10.10.123, your address
needs to be 10.10.10.x, and mask 255.255.255.0.
By TFTP: Uboot is in client mode, the address of the firmware must
be tftp://10.10.10.3/uboot.bin
Recovery:

MAC addresses:

- phy0 gets a valid-looking address:

- Calibration data for &pcie2 contains a valid address, however the
zeros in the right half look like it's not real:
8c:88:2b:00:00:1b
- Since it's an evaluation board and there is no solid information
about the MAC address assignment, the ethernet MAC address is left random.

This commit adds support for Xiaomi MiWiFi 3C device.
Xiaomi MiWifi 3C has almost the same system architecture
as the Xiaomi Mi WiFi Nano, which is already officially
supported by OpenWrt.
The differences are:
- Numbers of antennas (4 instead of 2). The antenna management
is done via the µC. There is no configuration needed in the
software code.
- LAN port assignments are different. LAN1 and WAN are
interchanged.
OpenWrt Wiki: https://openwrt.org/toh/xiaomi/mir3c
OpenWrt developers forum page:
https://forum.openwrt.org/t/support-for-xiaomi-mi-3c
Specifications:
- CPU: MediaTek MT7628AN (575MHz)
- Flash: 16MB
- RAM: 64MB DDR2
- 2.4 GHz: IEEE 802.11b/g/n with Integrated LNA and PA
- Antennas: 4x external single band antennas
- WAN: 1x 10/100M
- LAN: 2x 10/100M
- LED: 1x amber/blue/red. Programmable
- Button: Reset
MAC addresses as verified by OEM firmware:
use address source
LAN *:92 factory 0x28
WAN *:92 factory 0x28
2g *:93 factory 0x4
OEM firmware uses VLAN's to create the network interface for WAN and LAN.
Bootloader info:
The stock bootloader uses a "Dual ROM Partition System".
OS1 is a deep copy of OS2.
The bootloader start OS2 by default.
To force start OS1 it is needed to set "flag_try_sys2_failed=1".
How to install:
1- Use OpenWRTInvasion to gain telnet, ssh and ftp access.
https://github.com/acecilia/OpenWRTInvasion
(IP: 192.168.31.1 - Username: root - Password: root)
2- Connect to router using telnet or ssh.
3- Backup all partitions. Use command "dd if=/dev/mtd0 of=/tmp/mtd0".
Copy /tmp/mtd0 to computer using ftp.
4- Copy openwrt-ramips-mt76x8-xiaomi_miwifi-3c-squashfs-sysupgrade.bin
to /tmp in router using ftp.
5- Enable UART access and change start image for OS1.
```
nvram set uart_en=1
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set flag_try_sys2_failed=1
nvram commit
```
6- Installing Openwrt on OS1 and free OS2.
```
mtd erase OS1
mtd erase OS2
mtd -r write /tmp/openwrt-ramips-mt76x8-xiaomi_miwifi-3c-squashfs-sysupgrade.bin OS1
```
Limitations: For the first install the image size needs to be less
than 7733248 bits.

Specs (same as in v1):
- MT7628AN (575 MHz)
- 64MB RAM
- 8MB of flash (SPI NOR)
- 1x 10/100Mbps Ethernet (MT7628AN built-in switch with vlan)
- 1x 2.4GHz wifi (MT7628AN)
- 1x 5Ghz wifi (MT7612E)
- 4x LEDs (5 GPIO-controlled)
- 1x reset button
- 1x WPS button
The only and important difference between v1 & v3 is in flash memory
layout, so pls don't interchange these 2 builds!
Installation through web-ui (on OEM factory firmware):
1. Visit http://tplinkrepeater.net or the configured IP address of
your RE305 v3 (default 192.168.0.254).
2. Log in with the password you've set during initial setup of the
RE305 (there is no default password).
3. Go to Settings -> System Tools -> Firmware upgrade
4. Click Browse and select the OpenWRT image with factory.bin suffix
(not sysupgrade.bin)
5. A window with a progress bar will appear. Wait until it completes.
6. The RE305 will reboot into OpenWRT and serve DHCP requests on the
ethernet port.
7. Connect an RJ45 cable from the RE305 to your computer and access
LuCI at http://192.168.1.1/ to configure (or use ssh).
Disassembly:
Just unscrew 4 screws in the corners & take off the back cover.
Serial is exposed to the right side of the main board (in the middle)
and marked with TX/RX/3V3/GND, but the holes are filled with solder.
Installation through serial:
1. connect trough serial (1n8, baudrate=57600)
2. setup the TFTP server and connect it via ethernet
(ipaddr=192.168.0.254 of device, serverip=192.168.0.184 - your pc)
3. boot from a initramfs image first (choose 1 in the bootloader
options)
4. test it a bit with that, then proceed to run sysupgrade build
MAC addresses as verified by OEM firmware:
use OpenWrt address reference
LAN eth0 *:d2 label
2g wlan0 *:d1 label - 1
5g wlan1 *:d0 label - 2
The label MAC address can be found in config 0x2008.

Microchip PD69104B1 4-Channel PoE-PSE controller
TI TPS2373 PoE-PD controller
PoE-Controller
--------------
By default, the PoE outputs do not work with OpenWrt. To make them output
power, install the "poemgr" package from the packages feed.
This package can control the PD69104B1 PSE controller.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt" via SSH.
2. Add the uboot-envtools configuration file /etc/fw_env.config with the
following content
$ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config
3. Update the bootloader environment.
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
4. Transfer the OpenWrt sysupgrade image to the device using SCP.
5. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
6. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
7. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
8. Reboot the device. It should boot into OpenWrt.
Restore to UniFi
----------------
To restore the vendor firmware, follow the Ubiquiti UniFi TFTP
recovery guide for access points. The process is the same for
the Flex switch.

device and perform sysupgrade with it
5. Wait ~120 seconds to complete flashing
Notes:
- The hardware of WN-DX2033GR and WN-AX2033GR are almost the same, and
it is certified under the same radio-wave related regulations in Japan
- The last 0x80000 (512 KiB) in NAND flash is not used on stock firmware
- stock firmware requires "customized uImage header" (called as "combo
image") by MSTC (MitraStar Technology Corp.), but U-Boot doesn't
- uImage magic ( 0x0 - 0x3 ) : 0x434F4D42 ("COMB")

- 0x01: firmware
- 0x02: firmware_2
- debugflag : allow interrupt kernel loader, it's named as "Z-LOADER"
(Factory, 0xFE75)

Specification:

RAM: 64 MB DDR2
Flash: MX25L6405D SPI NOR 8 MB
WIFI: 2.4 GHz integrated
Ethernet: 5x 10/100/1000 Mbps QCA8337
USB: 1x 2.0

Installation
Connect to one of LAN (yellow) ethernet ports,
Open router configuration interface,
Go to Toolbox > Firmware,
Browse for OpenWrt factory image with dlf extension and hit Apply,
Wait few minutes, after the Power LED will stop blinking, the router is
ready for configuration.
Known issues
Some USB 2.0 devices work at full speed mode 1.1 only
MAC addresses
factory partition only contains one (binary) MAC address in 0x4.
u-boot-env contains four (ascii) MAC addresses, of which two appear
to be valid.
factory 0x4 **:**:**:**:b9:84 binary
u-boot-env ethaddr **:**:**:**:b9:84 ascii
u-boot-env wanaddr **:**:**:**:b9:85 ascii
u-boot-env wlanaddr 00:AA:BB:CC:DD:12 ascii
u-boot-env iNICaddr 00:AA:BB:CC:DD:22 ascii
The factory firmware only assigns ethaddr. Thus, we take the
binary value which we can use directly in DTS.
