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.

b123ffdf6e ath79: drop redundant status for gpio target-wide
All definitions of gpio in SoC DTSI files do not set status, i.e.
have it enabled. This drops all remaining redundant "status = okay"
definitions in descendent files (mostly older ones).

b2130b9ce8 ath79: add support for Devolo Magic 2 WIFI
This patch support Devolo Magic 2 WIFI, board devolo_dlan2-2400-ac.
This device is a plc wifi AC2400 router/extender with 2 Ethernet
ports, has a G.hn PLC and uses LCMP protocol from Home Grid Forum.

Hardware:
   SoC:         AR9344
   CPU:         560 MHz
   Flash:       16 MiB (W25Q128JVSIQ)
   RAM:         128 MiB DDR2
   Ethernet:    2xLAN 10/100/1000
   PLC:         88LX5152 (MaxLinear G.hn)
   PLC Flash:   W25Q32JVSSIQ
   PLC Uplink:  1Gbps MIMO
   PLC Link:    RGMII 1Gbps (WAN)
   WiFi:        Atheros AR9340 2.4GHz 802.11bgn
                Atheros AR9882-BR4A 5GHz 802.11ac
   Switch:      QCA8337, Port0:CPU, Port2:PLC, Port3:LAN1, Port4:LAN2
   Button:      3x Buttons (Reset, wifi and plc)
   LED:         3x Leds (wifi, plc white, plc red)
   GPIO Switch: 11-PLC Pairing (Active Low)
                13-PLC Enable
                21-WLAN power

MACs Details verified with the stock firmware:
   Radio1: 2.4 GHz &wmac     *:4c Art location: 0x1002
   Radio0: 5.0 GHz &pcie     *:4d Art location: 0x5006
   Ethernet        &ethernet *:4e = 2.4 GHz + 2
   PLC uplink      ---       *:4f = 2.4 GHz + 3
Label MAC address is from PLC uplink

OEM SSID: echo devolo-$(grep SerialNumber /dev/mtd1 | grep -o ...$)
OEM WiFi password: grep DlanSecurityID /dev/mtd1|tr -d -|cut -d'=' -f 2

Recommendations: Configure and link your PLC with OEM firmware
BEFORE you flash the device. PLC configuration/link should
remain in different memory and should work straight forward
after flashing.

Restrictions: PLC link detection to trigger plc red led is not
available. PLC G.hn chip is not compatible with open-plc-tools,
it uses LCMP protocol with AES-128 and requires different
software.

Notes: Pairing should be possible with gpio switch. Default
configuration will trigger wifi led with 2.4Ghz wifi traffic
and plc white led with wan traffic.

Flash instruction (TFTP):
 1. Set PC to fixed ip address 192.168.0.100
 2. Download the sysupgrade image and rename it to uploadfile
 3. Start a tftp server with the image file in its root directory
 4. Turn off the router
 5. Press and hold Reset button
 6. Turn on router with the reset button pressed and wait ~15 seconds
 7. Release the reset button and after a short time
    the firmware should be transferred from the tftp server
 8. Allow 1-2 minutes for the first boot.
