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.

Some boards using a QCA9556 or QCA9558 had their machine compatible
binding incorrectly set to qca,qca9557.

This applies several style adjustments that have been requested in
recent reviews to older DTS files. Despite making the code base more
consistent, this will also help to reduce review time when DTSes
are copy/pasted.
Applied changes:
- Rename gpio-keys/gpio-leds to keys/leds
- Remove node labels that are not used
- Use label property for partitions
- Prefix led node labels with "led_"
- Remove redundant includes
- Harmonize new lines after status property
- Several smaller style fixes

Upstream commit 6d4cd04 changes how the internal delays of the AR803x
based PHYs are enabled. With this commit, all internal delays are
disabled on driver probe and enabled based on the 'phy-mode' property in
the device-tree.
Before this commit, the RX delay was always enabled upon soft-reset
while the TX delay retained it's previous state. A hard reset enabled
the RX delay while the TX delay was disabled.
Because of this inconsistency, wrongly specified PHY-modes were working
correctly while the hardware was in a different state.
Fix the PHY-modes of some affected devices (and clean up misplaced
properties along the way) to keep the devices working flawlessly with
kernels >= 5.1.

Make sure you set a password for the root user as prompted on first
setup!
1. Upload OpenWRT sysupgrade image via SSH to the device.
Use /tmp as the destination folder on the device.
User is root, password the one set in the web interface.
2. Install OpenWRT with
> sysupgrade -n -F /tmp/<openwrt-image-name>
