8a3f19023b ath79: increase WS-AP3610 SPI frequency
The M25P80 used on the Siemens WS-AP3610 supports clock speeds up to 54
MHz. Thus, we can safely increase the maximum SPI frequency the flash
chip is controlled at to 50 MHz, increasing transfer speed.

3a4b751110 ath79: enable UART in SoC DTSI files
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.

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.

635f111148 ath79: drop and consolidate redundant chosen/bootargs
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.

d2b8ccb1c0 ath79: add support for Siemens WS-AP3610
Hardware
--------
SoC:  Atheros AR7161
RAM:  Samsung K4H511638D-UCCC
      2x 64M DDR1
SPI:  Micron M25P128 (16M)
WiFi: Atheros AR9160 bgn
      Atheros AR9160 an
ETH:  Broadcom BCM5481
LED:  Power (Green/Red)
      ETH (Green / Blue / Yellow)
          (PHY-controlled)
      WiFi 5 (Green / Blue)
      WiFi 2 (Green / Blue)
BTN:  Reset

Serial: Cisco-Style RJ45 - 115200 8N1

Installation
------------

1. Download the OpenWrt initramfs-image. Place it into a TFTP server
   root directory and rename it to 1401A8C0.img. Configure the TFTP
   server to listen at 192.168.1.66/24.

2. Connect the TFTP server to the access point.

3. Connect to the serial console of the access point. Attach power and
   interrupt the boot procedure when prompted (bootdelay is 1 second).

4. Configure the U-Boot environment for booting OpenWrt from Ram and
   flash:

   $ setenv boot_openwrt 'setenv bootargs; bootm 0xbf080000'
   $ setenv ramboot_openwrt 'setenv serverip 192.168.1.66;
     tftpboot; bootm'
   $ saveenv

5. Load OpenWrt into memory:

   $ run ramboot_openwrt

   Wait for the image to boot.

6. Transfer the OpenWrt sysupgrade image to the device. Write the image
   to flash using sysupgrade:

   $ sysupgrade -n /path/to/openwrt-sysuograde.bin
