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.

AR8327 datasheet[1] calls the register at address 0x0010
"Power-on Strapping Register". As it has nothing to do with "strip",
let's rename it to "POWER_ON_STRAP" to make it easier to grasp.

Specifications:
SoC: AR9344
DRAM: 128MB DDR2
Flash: 16MB SPI-NOR
2 Gigabit ethernet ports
2×2 2.4GHz on-board radio
miniPCIe slot that supports 5GHz radio
PoE 48V IEEE 802.3af/at - 24V passive optional
USB 2.0 header
Installation:
To install, either start tftp in bin/targets/ath79/generic/ and use
the u-boot prompt over UART:
tftpboot 0x80500000 openwrt-ath79-generic-compex_wpj344-16m-squashfs-sysupgrade.bin
erase 0x9f030000 +$filesize
erase 0x9f680000 +1
cp.b $fileaddr 0x9f030000 $filesize
boot
The cpximg file can be used with sysupgrade in the stock firmware (add
SSH key in luci for root access) or with the built-in cpximg loader.
The cpximg loader can be started either by holding the reset button
during power up or by entering the u-boot prompt and entering 'cpximg'.
Once it's running, a TFTP-server under 192.168.1.1 will accept the image
appropriate for the board revision that is etched on the board.
For example, if the board is labelled '6A08':
tftp -v -m binary 192.168.1.1 -c put openwrt-ath79-generic-compex_wpj344-16m-squashfs-cpximg-6a08.bin
MAC addresses:
<&uboot 0x2e010> *:99 (label)
<&uboot 0x2e018> *:9a
<&uboot 0x2e020> *:9b
<&uboot 0x2e028> *:9c
Only the first two are used (for ethernet), the WiFi modules have
separate (valid) addresses. The latter two addresses are not used.
