79f3f1358b ath79: Add support for Ubiquiti NanoBeam AC Gen2
CPU:         Atheros AR9342 rev 3 SoC
RAM:         64 MB DDR2
Flash:       16 MB NOR SPI
WLAN 2.4GHz: Atheros AR9342 v3 (ath9k)
WLAN 5.0GHz: QCA988X
Ports:       2x GbE

Flashing procedure is identical to other ubnt devices.
https://openwrt.org/toh/ubiquiti/common

Flashing through factory firmware
1. Ensure firmware version v8.7.0 is installed.
   Up/downgrade to this exact version.
2. Patch fwupdate.real binary using
   `hexdump -Cv /bin/ubntbox | sed 's/14 40 fe 27/00 00 00 00/g' | \
    hexdump -R > /tmp/fwupdate.real`
3. Make the patched fwupdate.real binary executable using
   `chmod +x /tmp/fwupdate.real`
4. Copy the squashfs factory image to /tmp on the device
5. Flash OpenWrt using `/tmp/fwupdate.real -m <squashfs-factory image>`
6. Wait for the device to reboot
(copied from Ubiquiti NanoBeam AC and modified)

To keep it consistent, we will add the gen1 variant to
the nanobeam ac gen1.

28a211808a ath79: create DTSI files for ubnt WA 1-/2-port devices
The ar9342 Ubiquiti WA devices appear to only have two different
network setups, based on the number of ethernet ports.
Create DTSI files for them to consolidate duplicate definitions.

50a76208bc ath79: fix nanobeam ac ethernet interface
In 4.14 the delays were not cleared, so setting "rgmii" as phy-mode
did not affect delays set by the bootloader. With 5.4 kernel the
situation changed and the ethernet interface stopped working.

"rgmii" requires rx and tx delays depending on the hardware circuit
and wiring. The mac or the phy can add these delays.
- "rgmii":  delays are controlled by the mac
- "rgmii-id": delays are controlled by the phy
More Information in Linux Kernel Tree:
Documentation/devicetree/bindings/net/ethernet-controller.yaml

"rgmii" should be the preferred mode, which allows the mac layer to
turn off the dealys completely if they are not needed. However, the
delays are not set correctly, which causes the ethernet interface
to be broken. Just taking the ethernetpart from the litebeam ac gen2
will fix the issue.

6f96a4d043 ath79: remove model name from LED labels
Currently, we request LED labels in OpenWrt to follow the scheme

  modelname:color:function

However, specifying the modelname at the beginning is actually
entirely useless for the devices we support in OpenWrt. On the
contrary, having this part actually introduces inconvenience in
several aspects:

  - We need to ensure/check consistency with the DTS compatible
  - We have various exceptions where not the model name is used,
    but the vendor name (like tp-link), which is hard to track
    and justify even for core-developers
  - Having model-based components will not allow to share
    identical LED definitions in DTSI files
  - The inconsistency in what's used for the model part complicates
    several scripts, e.g. board.d/01_leds or LED migrations from
    ar71xx where this was even more messy

Apart from our needs, upstream has deprecated the label property
entirely and introduced new properties to specify color and
function properties separately. However, the implementation does
not appear to be ready and probably won't become ready and/or
match our requirements in the foreseeable future.

However, the limitation of generic LEDs to color and function
properties follows the same idea pointed out above. Generic LEDs
will get names like "green:status" or "red:indicator" then, and
if a "devicename" is prepended, it will be the one of an internal
device, like "phy1:amber:status".

With this patch, we move into the same direction, and just drop
the boardname from the LED labels. This allows to consolidate
a few definitions in DTSI files (will be much more on ramips),
and to drop a few migrations compared to ar71xx that just changed
the boardname. But mainly, it will liberate us from a completely
useless subject to take care of for device support review and
maintenance.
To also drop the boardname from existing configurations, a simple
migration routine is added unconditionally.

Although this seems unfamiliar at first look, a quick check in kernel
for the arm/arm64 dts files revealed that while 1033 lines have
labels with three parts *:*:*, still 284 actually use a two-part
labelling *:*, and thus is also acceptable and not even rare there.

41cc7edc15 ath79: move dts-v1 statement to ath79.dtsi
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ath79, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent ath79.dtsi file already determines the DTS version, so
putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the parent
ath79.dtsi, which is (indirectly) included by all DTS files. All
other occurences are removed.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes to make sure the ath79.dtsi or its
descendants are always included first.

c08ddfce3f ath79: rename EEPROM to art
This renames all remaining occurrences of "EEPROM" to "art" to
further harmonize the partition labelling in ath79. This will
help to reduce the amount of user-space code and might be
beneficial when code is copy/pasted in the future.

Affected are only devices from Ubiquiti, where the XM board is
already using "art" in ath79.

d78e229903 ath79: Add support for Ubiquiti NanoBeam AC
The NanoBeam is a small AR9342 based directional 5 GHz AC CPE with hardware
almost identical to the Ubiquiti NanoStation AC loco. Over the NanoStation
AC loco it has 5 additional LEDs. Four of those LEDs are used as rssi
indicators, the fifth LED is used as an ethernet link/activity indicator.

CPU:   Atheros AR9342 SoC
RAM:   64 MB DDR2
Flash: 16 MB NOR SPI
WLAN:  QCA988X
Ports: 1x GbE

Flashing procedure is identical to the NanoStation AC loco and can be performed
either via serial or the factory firmware upgrade.

Serial flashing:

1. Connect to serial header on device (8N1 115200)
2. Power on device and enter uboot console
3. Set up tftp server serving an openwrt initramfs build
4. Load initramfs build using the command tftpboot in the uboot cli
5. Boot the loaded image using the command bootm
6. Copy squashfs openwrt sysupgrade build to the booted device
7. Use mtd to write sysupgrade to partition "firmware"
8. Reboot and enjoy

Flashing through factory firmware:

1. Ensure firmware version v8.5.0.36727 is installed. Up/downgrade to this exact version.
2. Patch fwupdate.real binary using `hexdump -Cv /bin/ubntbox | sed 's/14 40 fe fe/00 00 00 00/g' | hexdump -R > /tmp/fwupdate.real`
3. Make the patched fwupdate.real binary executable using `chmod +x /tmp/fwupdate.real`
4. Copy the squashfs factory image to /tmp on the device
5. Flash OpenWRT using `/tmp/fwupdate.real -m <squashfs-factory image>`
6. Wait for the device to reboot
