5c142aad7b ath79: switch some RedBoot based devices to OKLI loader
After the kernel has switched version to 5.10, JA76PF2 and
RouterStations lost the capability to sysupgrade the OpenWrt version.
The cause is the lack of porting the patches responsible for partial
flash erase block writing and these boards FIS directory and RedBoot
config partitions share the same erase block. Because of that the FIS
directory can't be updated to accommodate kernel/rootfs partition size
changes. This could be remedied by bootloader update, but it is very
intrusive and could potentially lead to non-trivial recovery procedure,
if something went wrong. The less difficult option is to use OpenWrt
kernel loader, which will let us use static partition sizes and employ
mtd splitter to dynamically adjust kernel and rootfs partition sizes.
On sysupgrade from ath79 19.07 or 21.02 image, which still let to modify
FIS directory, the loader will be written to kernel partition, while the
kernel+rootfs to rootfs partition.

The caveats are:
* image format changes, no possible upgrade from ar71xx target images
* downgrade to any older OpenWrt version will require TFTP recovery or
  usage of bootloader command line interface

To downgrade to 19.07 or 21.02, or to upgrade if one is already on
OpenWrt with kernel 5.10, for RouterStations use TFTP recovery
procedure. For JA76PF2 use instructions from this commit message:
commit 0cc87b3bac ("ath79: image: disable sysupgrade images for routerstations and ja76pf2"),
replacing kernel image with loader (loader.bin suffix) and rootfs
image with firmware (firmware.bin suffix).

3a4b751110 ath79: enable UART in SoC DTSI files
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.

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.

635f111148 ath79: drop and consolidate redundant chosen/bootargs
In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.

The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi

Note that while this tidies up master a lot, it might develop into a
frequent pitfall for backports.

231dc26867 treewide: remove dts-v1 identifier from DTSI files
The "/dts-v1/;" identifier is supposed to be put once at the beginning
of a device tree file. Thus, it makes no sense to provide it a second
time in to-be-included DTSI files.

This removes the identifier from all DTSI files in /target/linux.

Most of the DTS files in OpenWrt do contain the "/dts-v1/;". It is
missing for most of the following targets, though:
mvebu, ipq806x, mpc85xx, ipq40xx

This does not touch ipq806x for now, as the bump to 4.19 is close.

f4026ad24d ath79: DTS file style update and harmonization
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

0d23fd2ab2 treewide: dts: Remove default-state=off property from all gpio LED nodes
>From the Documentation/devicetree/bindings/leds/common.txt:

- default-state : The initial state of the LED. Valid values are "on", "off",
  and "keep". If the LED is already on or off and the default-state property is
  set the to same value, then no glitch should be produced where the LED
  momentarily turns off (or on). The "keep" setting will keep the LED at
  whatever its current state is, without producing a glitch.  The default is
  off if this property is not present.

So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.

d9753f0ec5 ath79, brcm63xx: Fix debounce-interval properties in gpio-keys-polled nodes
This patch fixes wrong usage of debounce-interval subnode property of
gpio-keys-polled nodes, which was used inproperly in parent node, but it
belongs to the subnodes, excerpt from the docs:

 Optional subnode-properties:
     - debounce-interval: Debouncing interval time in milliseconds.
       If not specified defaults to 5.

And the docs are up to date as the source code matches that description
as well:

 if (fwnode_property_read_u32(child, "debounce-interval",
                              &button->debounce_interval))
         button->debounce_interval = 5;

While at it, I've also re-formatted gpio-keys-polled nodes, usually just
adding new lines after every key subnode.

d03c89838e ath79: initial support for Ubiquiti RouterStation and RouterStation Pro
This adds a shared ar7161_ubnt_routerstation.dtsi as well as two other
.dts files that utilize it, ar7161_ubnt_routerstation.dts and
ar7161_ubnt_routerstation-pro.dts.

The modifications to generic-ubnt.mk, config-default, and base-files
necessary for image generation, parsing RedBoot FIS partitions, network
configuration, and sysupgrade are also included.

This reintroduces vital bits from platform_do_upgrade_combined() and its
supporting functions to /lib/upgrade/platform.sh, which were previously
removed from ath79 in 3e9d9f6225 "ath79:
sysupgrade: drop unused platform checks". The new function is called
"routerstation_do_upgrade" and will *only* work for the RouterStation
series of boards. It does however retain the ability to downgrade (e.g.
from master -> 17.01.x using sysupgrade -F).

All hardware is functional including the AR8216 switch (for the Pro),
wireless via ath5k/ath9k using the miniPCI slots, flash, USB, button,
and LED.

Switch and LAN/WAN configuration is the same as it is with the
equivalent ar71xx targets. MAC addresses are assigned based upon the
content stored in the RedBoot config partition.

Flashing via both sysupgrade and TFTP has been confirmed to work. Also,
the initramfs images are now raw .bin files instead of being wrapped in
a uImage (as they currently are in ar71xx), which makes them bootable
with RedBoot.

One notable difference to ar71xx is the inclusion of the RedBoot
"fconfig" utility (analogous to U-Boot’s fw_printenv/fw_setenv) in
DEVICE_PACKAGES. The FIS partitions are probed using the RedBoot MTD
parser’s DT binding, whose proper usage is mutually exclusive to
defining a separate fixed-partitions node for "RedBoot config". This
config partition contains the board's base MAC address. The lack of a
hard-coded flash location means that the mtd-mac-address property cannot
be used in the .dts, so instead fconfig is used to read the MAC
addresses from flash in userspace during first boot.
