3ea6125c50 ramips: mt7621-dts: describe switch PHYs and adjust PHY muxing
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.

01996b785d ramips: clean up useless dts partition labels
The previous NVMEM eeprom conversions[1][2] left a lot of partition
labels that were no longer used. They can be removed now.

f1c9afd801 ramips: mt7621-dts: mux phy0/4 to gmac1
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.

ba3d92c5a0 ramips: convert most mtd-mac-address cases in DTSI to nvmem
Convert most of the cases from mtd-mac-address to nvmem where
MAC addresses are set in the DTSI, but the partitions are only
located in the device DTS. This posed some problems earlier, since
in these cases we are using partitions before they are defined,
and the nvmem system did not seem to like that.

There have been a few different resolution approaches, based on
the different tradeoffs of deduplication vs. maintainability:

 1. In many cases, the partition tables were identical except for
    the firmware partition size, and the firmware partition was
    the last in the table.
    In these cases, the partition table has been moved to the
    DTSI, and only the firmware partition's "reg" property has
    been kept in the DTS files. So, the updated nvmem definition
    could stay in the DTSI files as well.

 2. For all other cases, splitting up the partition table would
    have introduced additional complexity. Thus, the nodes to be
    converted to nvmem have been moved to the DTS files where the
    partitioning was defined.

 3. For Netgear EX2700 and WN3000RP v3, the remaining DTSI file
    was completely dissolved, as it was quite small and the name
    was not really nice either.

 4. The D-Link DIR-853 A3 was converted to nvmem as well, though
    it is just a plain DTS file not taken care of in the first
    wave.

In addition, some minor rearrangements have been made for tidyness.

Not covered (yet) by this patch are:

 * Various unielec devices
 * The D-Link DIR-8xx family

6639623e75 ramips: add support for D-Link DIR-853 A3
Specifications:
* SoC: MT7621AT
* RAM: 256MB
* Flash: 128MB NAND flash
* WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC
* LAN: 5x1000M
* Firmware layout is Uboot with extra 96 bytes in header
* Base PCB is DIR-1360 REV1.0
* LEDs Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue,
  USB Blue
* Buttons Reset,WPS, Wifi

MAC addresses on OEM firmware:

lan      factory 0xe000   f4:*:*:a8:*:65  (label)
wan      factory 0xe006   f4:*:*:a8:*:68
2.4 GHz  [not on flash]   f6:*:*:c8:*:66
5.0 GHz  factory 0x4      f4:*:*:a8:*:66

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:

       5g                 2.4g         increment
 f4:XX:XX:a8:XX:66  f6:XX:XX:c8:XX:66  +0x20
 x0:xx:xx:68:xx:xx  x2:xx:xx:48:xx:xx  -0x20
 x4:xx:xx:6a:xx:xx  x6:xx:xx:4a:xx:xx  -0x20

Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

Flashing instruction:

The Dlink "Emergency Room" cannot be accessed through the reset
button on this device. You can either use console or use the
encrypted factory image availble in the openwrt forum.

Once the encrypted image is flashed throuh the stock Dlink web
interface, the sysupgrade images can be used.

Header pins needs to be soldered near the WPS and Wifi buttons.

The layout for the pins is (VCC,RX,TX,GND). No need to connect the VCC.

the settings are:

Bps/Par/Bits          : 57600 8N1
Hardware Flow Control : No
Software Flow Control : No

Connect your client computer to LAN1 of the device
Set your client IP address manually to 192.168.0.101 / 255.255.255.0.
Call the recovery page or tftp for the device at http://192.168.0.1
Use the provided emergency web GUI to upload and flash a new firmware to
the device

At the time of adding support the wireless config needs to be set up by
editing the wireless config file:

 * Setting the country code is mandatory, otherwise the router loses
   connectivity at the next reboot. This is mandatory and can be done
   from luci. After setting the country code the router boots correctly.
   A reset with the reset button will fix the issue and the user has to
   reconfigure.

 * This is minor since the 5g interface does not come up online although
   it is not set as disabled. 2 options here:

   1- Either run the "wifi" command. Can be added from LUCI in system -
      startup - local startup and just add wifi above "exit 0".

   2- Or add the serialize option in the wireless config file as shown
      below. This one would work and bring both interfaces automatically
      at every boot:

      config wifi-device 'radio0'
          option serialize '1'

      config wifi-device 'radio1'
          option serialize '1'
