1ed18edaec ath79: remove num-chipselects from SPI controller
The num-chipselects property is only valid for bit-banged spi-gpio [1].

For the generic SPI controller bindings, num-cs would be the correct
property [2].

Since num-cs is not required on ath79 either, just drop the lines.

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.

dc1280ef65 ath79: enable gpio on ar933x by default
All other SoC DTSI files have gpio enabled by default, only
ar9330/ar9331 disable it by default, only to have it enabled again
afterwards for each individual device.

So, do not disable it in the first place, and drop all device-specific
status statements afterwards.

2b1baf9b16 ath79: remove redundant mtd-mac-address for wmac
For several devices, wmac MAC address is set from art 0x1002
explicitly by using mtd-mac-address although mtd-cal-data is
pulled from art 0x1000.

With the MAC address in 0x1002, the driver should automatically
use it when reading caldata from 0x1000. Thus, remove the
redundant mtd-mac-address for those devices.

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.

dadcd3dd98 ath79: eg200: enable status led usage
This enables using the "eTactica" LED during boot, to indicate failsafe,
and during upgrade, while still leaving the LED alone for normal
operation.  This brings the device more in line with how other devices
work, and makes the failsafe functionality easier to use and understand.

Properly disable the SoC's internal Switch LEDs on the pinmux.

0d23fd2ab2 treewide: dts: Remove default-state=off property from all gpio LED nodes
>From the Documentation/devicetree/bindings/leds/common.txt:

- default-state : The initial state of the LED. Valid values are "on", "off",
  and "keep". If the LED is already on or off and the default-state property is
  set the to same value, then no glitch should be produced where the LED
  momentarily turns off (or on). The "keep" setting will keep the LED at
  whatever its current state is, without producing a glitch.  The default is
  off if this property is not present.

So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.

bc41fb7efe ath79: Define firmware partition format to all boards where applicable
Parsing "firmware" partition (to create kernel + rootfs) was implemented
using OpenWrt downstream code enabled by CONFIG_MTD_SPLIT_FIRMWARE. With
recent upstream mtd changes we can do it in a more clean way for DTS
targets. It just requires adding a proper "compatible" string to the
"firmware" partition node.
