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.

5e86877f36 ath79: correctly define WiFi switch for TL-WR841ND v8
The TL-WR841ND v8 feature a WiFi switch instead of a button.
This adds the corresponding input-type to prevent booting into
failsafe regularly.

This has been defined correctly in ar71xx, but was overlooked
when migrating to ath79. In contrast, the TL-WR842ND v2, which
has the key set up as switch in ar71xx, actually has a button.
The TL-MR3420 v2 has a button as well and is set up correctly
for both targets. (Information based on TP-Link user guide)

Note:

While looking into this, I found that support PR for TL-MR3420 v2
switched reset button to ACTIVE_HIGH. However, the other two
device still use ACTIVE_LOW. This seems strange, but I cannot
verify it lacking the affected devices.

18c95c9d6e ath79: add gpio4 pinmux on TL-WR841N/ND v8, WR842N v2, MR3420 v2
This adds a pinmux to the shared DTSI for TP-Link TL-WR841N/ND v8,
TL-WR842N v2 and TL-MR3420 v2. It is supposed to be the equivalent
of:

/* config gpio4 as normal gpio function */
ath79_gpio_output_select(TL_MR3420V2_GPIO_USB_POWER,AR934X_GPIO_OUT_GPIO);

This allows to enable USB power on these devices.

While at it, move the jtag_disable_pins to &gpio node and remove the
redundant status=okay there.

Tested on TP-Link TL-WR842N v2.

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

50fdc0374b ath79: provide label MAC address
This patch adds the label MAC address for several devices in
ath79.

Some devices require setting the MAC address in 02_network:

For the following devices, the netif device can be linked in
device tree, but the MAC address cannot be read:
- alfa-network,ap121f
- avm,fritz300e
- ubnt-xm devices

For the following devices, label MAC address is tied to lan or
wan, so no node to link to exists in device tree:
- adtran,bsap1800-v2
- adtran,bsap1840
- dlink,dir-842-c1/-c2/-c3
- engenius,ecb1750
- iodata,etg3-r

95dfeabf26 ath79: create DTSI for ar9341 TP-Link devices
This patch creates a shared DTSI for the TP-Link devices based
on ar9341 as those share a lot of definitions.

While at it, change from gpio-keys-polled to gpio-keys, remove
unused pll-data and remove some inherited stuff, too.
