e826b64294 ath79: convert remaining mtd-mac-address cases to nvmem
Since the nvmem-based approach for retrieving MAC addresses
appears to depend on the addresses being set up after the
partitions, it is no longer possible to keep the MAC address
setup in shared DTSI files while the partitions itself are
set up in DTS files for the individual devices.

In ath79 the firmware partition is typically located somewhere
"in the middle" of the partition table. Thus, it's not trivial
to share the partitions containing MAC address information in
a common DTSI (like we did in some cases on ramips).

In this commit, MAC address setup is thus moved to the relevant
partitions, and in most cases needs to be duplicated. While
the duplication is not really nice, it eventually provides a
cleaner and more tidy setup, making the DTS(I) file
fragmentation a bit more logical. This should also help
with adding new devices, as information is distributed across
less locations.

For consistency, this commit also moves the mtd-cal-data property
"down" together with the MAC address setup, so it's not based
on a partition before the latter is defined either. (This is
only done for those files touched due to nvmem conversion.)

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.

5e86877f36 ath79: correctly define WiFi switch for TL-WR841ND v8
The TL-WR841ND v8 feature a WiFi switch instead of a button.
This adds the corresponding input-type to prevent booting into
failsafe regularly.

This has been defined correctly in ar71xx, but was overlooked
when migrating to ath79. In contrast, the TL-WR842ND v2, which
has the key set up as switch in ar71xx, actually has a button.
The TL-MR3420 v2 has a button as well and is set up correctly
for both targets. (Information based on TP-Link user guide)

Note:

While looking into this, I found that support PR for TL-MR3420 v2
switched reset button to ACTIVE_HIGH. However, the other two
device still use ACTIVE_LOW. This seems strange, but I cannot
verify it lacking the affected devices.

Fixes: FS#2733
Fixes: 9601d94138 ("add support for TP-Link TL-WR841N/ND v8")

95dfeabf26 ath79: create DTSI for ar9341 TP-Link devices
This patch creates a shared DTSI for the TP-Link devices based
on ar9341 as those share a lot of definitions.

While at it, change from gpio-keys-polled to gpio-keys, remove
unused pll-data and remove some inherited stuff, too.

e7ab1b5173 ath79: migrate TP-Link TL-MR3420v2 to ath79
Specifications:
- SoC: ar9341
- RAM: 32M
- Flash: 4M
- Ethernet: 5x FE ports
- WiFi: ar9341-wmac

Flash instruction:
Upload generated factory firmware on vendor's web interface.

This changes the key assignment compared to ar71xx support of this
device, since of the two keys on the device one is used as combined
Reset/WPS and the second one as WiFi on/off button.
Despite, the reset button required GPIO_ACTIVE_HIGH to work correctly.
