The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.
Where the majority of devices is using it, also move the serial0
alias to the DTSI.
*) Since GL-USB150 even defines serial0 alias, the missing uart
is probably just a mistake. Anyway, disable it for now so this
patch stays cosmetic.

None of the spi drivers on ath79 uses the num-cs property.

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.

On ar7240/ar7241 the mdioX node with the builtin-switch is enabled
in the DTSI files, but the parent ethX node is left disabled. It
only gets enabled per device or device family, and has not been
enabled at all yet for the TP-Link WA devices with ar7240, making
the switch unavailable there.
This patch makes sure ð0/ð1 nodes are enabled together with
the &mdio0/&mdio1 nodes containing the builtin-switch.
For ar7240_tplink_tl-wa.dtsi, ð0 is properly hidden again via
compatible = "syscon", "simple-mfd";
This partially fixes FS#2887, however it seems dmesg still does
not show cable (dis)connect in dmesg for ar7240 TP-Link WA
devices.

Partitioning notes:
Vendor firmware (based on CameoAP99) defines two additional partitions:
"mac" @0x3b0000, size 0x10000 and "lp" @0x3c0000, size 0x30000.
The "mac" partition stores LAN MAC address and hardware board name.
However, the vendor firmware uses addresses from "nvram" partition, and
the board name is used only for informational purposes in the Web
interface (included in the pages' header), not affecting the firmware
image check.
The "lp" partition is supposed to contain a "language pack" (which can
be used to add an additional language support to the Web interface) and
is flashed separately, using the vendor firmware upgrade page.
Since these partitions are absolutely useless for OpenWrt and
overwriting them doesn't prevent downgrading to obsolete vendor
firmware, this patch appends the valueable space to "firmware".
Installation instructions:
- Upgrade from OpenWrt ar71xx with "sysupgrade -f -n"
or
- Upload as a firmware update via the vendor Web-interface
or
- Connect UART and use "loady" to upload and run OpenWrt initramfs
image, then sysupgrade from it (TFTP client doesn't work)
or
- Before powering up hold "reset" button and keep it pressed for about
15 seconds after, then access fail safe Web server on 192.168.0.1 (the
old uIP TCP/IP protocol stack is not compatible with modern Linux, the
kernel, so you'll need to use some other OS to do this). Can be
performed without a Web-browser too:
curl http://192.168.0.1/cgi/index \
-F Send=@openwrt-ath79-tiny-dlink_dir-615-e4-squashfs-factory.bin
