The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.
Where the majority of devices is using it, also move the serial0
alias to the DTSI.
*) Since GL-USB150 even defines serial0 alias, the missing uart
is probably just a mistake. Anyway, disable it for now so this
patch stays cosmetic.

None of the spi drivers on ath79 uses the num-cs property.

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.

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.

On Comfast CF-E130N v2 and Mikrotik LHG HB board, the config
found in DTS appears to be strange:
- eth0 has "syscon","simple-mfd" set although it's not enabled
- eth1 is enabled redundantly (already "okay" in qca953x.dtsi)
- phy-handle is set for eth1 in DTS although it has a fixed-link
in qca953x.dtsi
This seems like a copy-paste gone wrong. Remove the named options.
Run-tested on MikroTik LHG 2.

This patch adds support for the COMFAST CF-E130N v2, an outdoor wireless
CPE with a single Ethernet port and a 802.11bgn radio.
Specifications:
- QCA9531 SoC
- 1x 10/100 Mbps Ethernet with PoE-in support
- 64 MB of RAM (DDR2)
- 16 MB of FLASH
- 5 dBi built-in antenna
- POWER/LAN/WLAN green LEDs
- 4x RSSI LEDs (2x red, 2x green)
- UART (115200 8N1) and GPIO (J9) headers on PCB
Flashing instructions:
The original firmware is based on OpenWrt so a sysupgrade image can be
installed via the stock web GUI.
The U-boot bootloader also contains a backup TFTP client to upload the
firmware from. Upon boot, it checks its ethernet network for the IP
192.168.1.10. Host a TFTP server and provide the image to be flashed as
file firmware_auto.bin.
MAC address setup:
The art partition contains four consecutive MAC addresses:
0x0 aa:bb:cc:xx:xx:c4
0x6 aa:bb:cc:xx:xx:c6
0x1002 aa:bb:cc:xx:xx:c5
0x5006 aa:bb:cc:xx:xx:c7
However, the manufacturer in its infinite wisdom decided that one address
is enough and both eth0 and WiFi get the MAC address from 0x0 (yes, that's
overwriting the existing and valid address in 0x1002). This is obviously
also the address on the device's label.
