ab47e21472 ath79: qca955x: remove redundant phy-mode
phy-mode is already set to rgmii for eth0 and sgmii for eth1 in
qca955x.dtsi, no need to do that again in the device DTS files.

72bd92bea0 ath79: drop num-cs for SPI controller
None of the spi drivers on ath79 uses the num-cs property.

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.

cd09f26660 ath79: add support for D-Link DAP-2695-A1
Hardware:
* SoC: Qualcomm Atheros QCA9558
* RAM: 256MB
* Flash: 16MB SPI NOR
* Ethernet: 2x 10/100/1000 (1x 802.3at PoE-PD)
* WiFi 2.4GHz: Qualcomm Atheros QCA9558
* WiFi 5GHz: Qualcomm Ahteros QCA9880-2R4E
* LEDS: 1x 5GHz, 1x 2.4GHz, 1x LAN1(POE), 1x LAN2, 1x POWER
* Buttons: 1x RESET
* UART: 1x RJ45 RS-232 Console port

Installation via stock firmware:
* Install the factory image via the stock firmware web interface

Installation via bootloader Emergency Web Server:
* Connect your PC to the LAN1(PoE) port
* Configure your PC with IP address 192.168.0.90
* Open a serial console to the Console port (115200,8n1)
* Press "q" within 2s when "press 'q' to stop autoboot" appears
* Open http://192.168.0.50 in a browser
* Upload either the factory or the sysupgrade image
* Once you see "write image into flash...OK,dest addr=0x9f070000" you
  can power-cycle the device. Ignore "checksum bad" messages.

Setting the MAC addresses for the ethernet interfaces via
/etc/board.d/02_network adds the following snippets to
/etc/config/network:

config device 'lan_eth0_1_dev'
        option name 'eth0.1'
        option macaddr 'xx:xx:xx:xx:xx:xx'

config device 'wan_eth1_2_dev'
        option name 'eth1.2'
        option macaddr 'xx:xx:xx:xx:xx:xx'

This would result in the proper MAC addresses being set for the VLAN
subinterfaces, but the parent interfaces would still have a random MAC
address. Using untagged VLANs could solve this, but would still leave
those extra snippets in /etc/config/network, and then the device VLAN
setup would differ from the one used in ar71xx. Therefore, the MAC
addresses of the ethernet interfaces are being set via preinit instead.

The bdcfg partition contains 4 MAC address labels:
 - lanmac
 - wanmac
 - wlanmac
 - wlanmac_a

The first 3 all contain the same MAC address, which is also the one on
the label.
