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.

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.

The tp-link safeloader devices typically contain a partition
"default-mac" which stores the MAC addresses. It is followed by other
partitions containing device info, like
{"default-mac", 0x610000, 0x00020},
{"pin", 0x610100, 0x00020},
{"product-info", 0x611100, 0x01000},
In DTS, we typically assign a 0x10000 sized partition for these,
which is mostly labelled "mac" or "info". In rarer cases, the
partitions have been enclosed in a larger "tplink" or "config"
partition.
However, when comparing different devices, the implementation appears
relatively arbitrary at the moment.
Thus, this PR aims at harmonizing these partitions by always using
the name "info" for the DTS partition containing "default-mac".
"info" is preferred over "mac" as we never just have "default-mac"
alone, but always some other device-info partitions as well.
While at it, this also establishes a similar partitioning for the
few devices where the "info" partitions are part of a bigger
unspecific "config" partition or similar.
Besides the harmonization itself, this also allows to merge a few
cases in 11-ath10k-caldata.

This patch is based on #1689 and adds support for TP-Link Archer
C6 v2 (US) and A6 (US/TW).
The hardware is the same as EU and RU variant, except for GPIOs
(LEDS/Buttons), flash(chip/partitions) and UART being available
on the board.
- SOC: Qualcomm QCA9563 @ 775MHz
- Flash: GigaDevice GD25Q127CS1G (16MiB)
- RAM: Zentel A3R1GE40JBF (128 MiB DDR2)
- Ethernet: Qualcomm QCA8337N: 4x 1Gbps LAN + 1x 1Gbps WAN
- Wireless:
- 2.4GHz (bgn) QCA9563 integrated (3x3)
- 5GHz (ac) Qualcomm QCA9886 (2x2)
- Button: 1x power, 1x reset, 1x wps
- LED: 6x LEDs: power, wlan2g, wlan5g, lan, wan, wps
- UART: 115200, 8n1 (header available on board)
Known issues:
- Wireless: 5GHz is known to have lower RSSI signal, it affects speed and range.
Flash instructions:
Upload openwrt-ath79-generic-tplink_archer-c6-v2-us-squashfs-factory.bin
via the router Web interface.
Flash instruction using tftp recovery:
1. Connect the computer to one of the LAN ports of the router
2. Set the computer IP to 192.168.0.66
3. Start a tftp server with the OpenWrt factory image in the
tftp root directory renamed to ArcherA6v2_tp_recovery.bin.
4. Connect power cable to router, press and hold the
reset button and turn the router on
5. Keep the reset button pressed until the WPS LED lights up
6. Wait ~150 seconds to complete flashing
Flash partitioning: I've followed #1689 for defining the partition layout
for this patch. The partition named as "tplink" @ 0xfd0000 is marked
as read only as it is where some config for stock firmware are stored.
On stock firmware those stock partitions starts at 0xfd9400 however
I had not been able to make it functional starting on the same address as
on stock fw, so it has been partitioned following #1689 and not the stock
partition layout for this specific partition. Due to that firmware/rootfs
partition lenght is 0xf80000 and not 0xf89400 as stock.
According to the GPL code, the EU/RU/JP variant does have different GPIO pins
assignment to LEDs and buttons, also the flash memory layout is different.
