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.

In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.
The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi
Note that while this tidies up master a lot, it might develop into a
frequent pitfall for backports.

There are at least 3 different chips in the Scorpion series of SoCs.
Rename the common DTSI to better reflect it's purpose for the whole
series.
Also rename the compatible bindings from qca,ar9557 and qca,qca9557
to qca,qca9550.

This commit ports the device from ar71xx to the ath79 target and
modifies the partition layout.
1. Firmware is installed to nand flash.
2. Modify the uboot-env parameter to boot from the nand flash.
3. The kernel size is extended to 5M.
4.nor flash retains the oem firmware.

MAC address overview:
All mac addresses are stored in the art partition.
eth0: 0x0
eth1: 0x6
ath9k: 0xc
ath10k: 0x12
No valid addresses in 0x1002 and 0x5006. All addresses match the OEM
firmware.
Install from oem firmware.
Enable ssh service:
Connect to the router web, click professional, click system-startup,
and add dropbear in the local startup input box. Click
system-administration, delete ssh-key, and replace your ssh pub key.
Restart the router.
1.Upload openwrt firmware to the device
scp openwrt-snapshot-r11365-df60a0852c-ath79-nand-domywifi_dw33d-\
squashfs-factory.bin root@192.168.10.1:/tmp
2.modify uboot-env.
ssh login to the device:
fw_setenv bootcmd 'nboot 0x8050000 0;bootm || bootm 0x9fe80000'
Run the fw_printenv command to check if the settings are correct.
3.Write openwrt firmware.
ssh login to the device:
mtd -r write /tmp/openwrt-snapshot-r11365-df60a0852c-ath79-nand-\
domywifi_dw33d-squashfs-factory.bin /dev/mtd6
The device will restart automatically and the openwrt firmware
installation is complete.
Restore oem firmware.just erase the kernel partition and the ubi
partition.
ssh login to the device:
mtd erase /dev/mtd4
mtd -r erase /dev/mtd5
Reboot the device
