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.

c0a80b7125 ath79: rename qca9557.dtsi to qca955x.dtsi
There are at least 3 different chips in the Scorpion series of SoCs.
Rename the common DTSI to better reflect it's purpose for the whole
series.

Also rename the compatible bindings from qca,ar9557 and qca,qca9557
to qca,qca9550.

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

8961d2268e ath79: convert devices to interrupt-driven gpio-keys
This converts all remaining devices to use interrupt-driven
gpio-keys compatible instead of gpio-keys-polled.
The poll-interval is removed.

Only ar7240_netgear_wnr612-v2 is kept at gpio-keys-polled, as
this one is using ath9k keys.

ee34740ca3 ath79: add suport for EnGenius EPG5000
EnGenius EPG5000 (v1.0.0, marketed as IoT Gateway) is a dual band
wireless router.

Specification
SoC:		Qualcomm Atheros QCA9558
RAM:		256 MB DDR2
Flash:		16 MB SPI NOR
WIFI:		2.4 GHz 3T3R integrated
		5 GHz 3T3R QCA9880 Mini PCIe card
Ethernet:	5x 10/100/1000 Mbps QCA8337N
USB:		1x 2.0
LEDS:		4x GPIO controlled
Buttons:	2x GPIO controlled
UART:		4 pin header, starting count from white triangle on PCB
		1. VCC 3.3V, 2. GND, 3. TX, 4. RX
		baud: 115200, parity: none, flow control: none

Installation
1. Connect to one of LAN (yellow) ethernet ports,
2. Open router configuration interface,
3. Go to Tools > Firmware,
4. Select OpenWrt factory image with dlf extension and hit Apply,
5. Wait few minutes, after the Power LED will stop blinking, the router
   is ready for configuration.

Alternative installation
1. Prepare TFTP server with OpenWrt sysupgrade image,
2. Connect to one of LAN (yellow) ethernet ports,
3. Connect to UART port (leaving out VCC pin!),
4. Power on router,
5. When asked to enter a number 1 or 3 hit 2, this will select flashing
   image from TFTP server option,
6. You'll be prompted to enter TFTP server ip (default is 192.168.99.8),
   then router ip (default is 192.168.99.9) and for last, image name
   downloaded from TFTP server (default is uImageESR1200_1750),
7. After providing all information U-Boot will start flashing the image,
   You can observe progress on console, it'll take few minutes and when
   the Power LED will stop blinking, router is ready for configuration.

Additional information
If connected to UART, when prompted for number on boot, one can enter
number 4 to open bootloader (U-Boot) command line.
OEM firmware shell password is: aigo3d0a0tdagr
useful for creating backup of original firmware.
When doing upgrade from OpenWrt ar71xx image, it is recomended to not keep
the old configuration.
