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.

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.

c1db564cbc ath79: dts: fix ja76pf2 spi frequency
The frequency was filled acording the information from datasheet for
particular chip (Winbond 25Q128BVFG). Unfortunately this led to
coruption and introduced bad blocks on the chip. Reducing the frequency
to commonly used in ath79, made the board more stable and no new bad
blocks were spoted.

b3a0c97b8c ath79: add support for jjPlus JA76PF2
jjPlus JA76PF2 (marketed as IntellusPro2) is a network embedded board.

Specification
SoC:		Atheros AR7161
RAM:		64 MB DDR
Flash:		16 MB SPI NOR
Ethernet:	2x 10/100/1000 Mbps AR8316
		LAN (CN11), WAN/PoE (CN6 - close to power barrel
		connector, 48 V)
MiniPCI:	2x
LEDS:		4x, which 3 are GPIO controlled
Buttons:	2x GPIO controlled
		Reset (SW1, closer to ethernet ports), WPS (SW2)
Serial:		1x (only RX and TX are wired)
		baud: 115200, parity: none, flow control: none

Currently there is one caveat compared to ar71xx target images as the
MAC addresses are random on every reboot. To remedy this one needs to
store the WAN MAC address in RedBoot configuration. OpenWrt on first
boot, after flashing, will read out the address and assign proper ones
to both WAN and LAN ports. It is iportant to NOT keep the old
configuration when doing sysupgrade from ar71xx.

Upgrading from OpenWrt ar71xx image
1. Connect to serial port,
2. Download OpenWrt sysupgrade image to /tmp directory and flash it
   with:
    sysupgrade -n <openwrt_sysupgrade_image_name>
3. After writing new image OpenWrt will reboot, now interrupt boot
   process and enter RedBoot (bootloader) command line by pressing
   Ctrl+C,
4. Enter following commands (replace variable accordingly),
    set_mac (to view MAC addresses)
    alias ethaddr <wan_port_mac_adress>
    (confirm storing the value by inputting y and pressing Enter)
    reset
5. Now board should restart and boot OpenWrt with proper MAC addresses.

Installation
1. Prepare TFTP server with OpenWrt initramfs image,
2. Connect to WAN ethernet port,
3. Connect to serial port,
4. Power on the board and enter RedBoot (bootloader) command line by
   pressing Ctrl+C,
5. Enter following commands (replace variables accordingly):
    set_mac (to view MAC addresses)
    alias ethaddr <wan_port_mac_address>
    (confirm storing the value by inputting y and pressing Enter)
    ip_adress -l <board_ip_adress>/24 -h <tftp_server_ip_adress>
    load -r -b 0x80060000 <openwrt_initramfs_image_name>
    exec -c ""
6. Now board should boot OpenWrt initramfs image,
7. Download OpenWrt sysupgrade image to /tmp directory and flash it
   with:
    sysupgrade <openwrt_sysupgrade_image_name>
8. Wait few minutes, after the D2 LED will stop blinking, the board
   is ready for configuration.
