1b44ecc2d7 samsung: add subtarget condition for device
The only device in samsung target is meant to be built with s5pv210
subtarget. Thus, though this won't make a difference for a
one-subtarget target, already add the condition to the Makefile to
make the assignment obvious.

6e70e4a071 samsung: use soc_vendor_model scheme for DTS file name
This patch changes the samsung target to calculate the DTS file name
from vendor and device name and the SOC (i.e. subtarget) following
the common scheme:

soc_vendor_model.dts

This also updates the device definition name to make compatible,
image name, menuconfig name and DTS name consistent.

1e7c6381f0 ramips: convert TP-Link MT7620 boards to tpt trigger
This converts all MediaTek MT7620 boards from TP-Link to use the now
supported WiFi throughput LED trigger. This way, the LED state now
covers all VAPs regardless of their name.

Also align all single-WiFi LEDs to represent the state of the 2.4GHz
radio. This was not always the case previously, as later-added support
for the MT7610 altered the phy probing order.

a3010a7f8d ramips: add support for TP-Link RE200 v1
TP-Link RE200 v1 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas. It's based on MediaTek MT7620A+MT7610EN.

Specifications
--------------

- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- UART header on PCB (57600 8n1)
- 8x LED (GPIO-controlled; only 6 supported), 2x button

There are 2.4G and 5G LEDs in red and green which are controlled
separately. The 5G LED is currently not supported, since the GPIOs couldn't
be determined.

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

Web Interface
-------------

It is possible to upgrade to OpenWrt via the web interface. However, the
OEM firmware upgrade file is required and a tool to fix the MD5 sum of
the header. This procedure overwrites U-Boot and there is not failsafe /
recovery mode present! To prepare an image, you need to take the header
and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and
attach the factory image to it. Then fix the header MD5Sum1.

Serial console
--------------

Opening the case is quite hard, since it is welded together. Rename the
OpenWrt factory image to "test.bin", then plug in the device and quickly
press "2" to enter flash mode (no line feed). Follow the prompts until
OpenWrt is installed.

Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console. Since the web upgrade overwrites
the boot loader, you might also brick your device.

Additional notes
----------------

MAC address assignment is based on stock-firmware. For me, the device
assigns the MAC on the label to Ethernet and the 2.4G WiFi, while the 5G
WiFi has a separate MAC with +2.

*:88    Ethernet/2.4G    label, uboot 0x1fc00, userconfig 0x0158
*:89    unused           userconfig 0x0160
*:8A    5G               not present in flash

This seems to be the first ramips device with a TP-Link v1 header. The
original firmware has the string "EU" embedded, there might be some region-
checking going on during the firmware upgrade process. The original
firmware also contains U-Boot and thus overwrites the boot loader during
upgrade.
In order to flash back to stock, the first header and U-Boot need to be
stripped from the original firmware.

5e5e92b7c3 ath79: generate firmware image for aircube-isp
This adds a "factory" image for the aircube-isp devices. Note that the
firmware can't be uploaded without prior special preparation. For the
most recent instructions on how to do that, visit the OpenWRT wiki page
of the Ubiquiti airCube ISP for details:

https://openwrt.org/toh/ubiquiti/ubiquiti_aircube_isp

Current procedure:

With the original firmware 2.5.0 it is possible to upload and execute a
script via the configuration. To do that download and unpack the
original configuration, adapt uhttpd config to execute another lua
handler (placed in the config directory) and pack and upload it again.

The lua handler can call a script that mounts an overlayfs and modifies
the "fwupdate.real" binary so that an unsigned image is accepted. The
overlayfs is necessary because a security system (called tomoyo) doesn't
allow binaries in other locations than /sbin/fwupdate.real (and maybe
some more) to access the flash when executed via network.

A big thanks to Torvald Menningen (Snap) from the OpenWRT forum for
finding out how to patch the binary so that it accepts an unsigned
image.

The current step-by-step procedure is:

- Use a version 2.5.0 of the original firmware. This is important
  because a binary file will be modified.
- Download a configuration.
- Unpack it (it's just a tar gz file without an ending).
- Add the following to uhttpd:

``````
config 'uhttpd' 'other'
	list listen_http    0.0.0.0:8080
	list listen_http    [::]:8080
	option 'home'       '/tmp/persistent/config/patch/www'
	option lua_prefix   '/lua'
	option lua_handler  '/tmp/persistent/config/patch/handler.lua'
``````

- Create a `patch` subfolder.
- Create a `patch/www` subfolder.
- Create a `patch/handler.lua` with the following content:

``````
function handle_request(env)
    uhttpd.send("Status: 200 OK\r\n")
    uhttpd.send("Content-Type: text/plain\r\n\r\n")

    local command = "/bin/sh /tmp/persistent/config/patch/patch.sh 2>&1"

    local proc = assert(io.popen(command))
    for line in proc:lines() do
        uhttpd.send(line.."\r\n")
    end
    proc:close()
end
``````

- Create a `patch/patch.sh` with the following content:

``````
#!/bin/sh -x

set -e
set -u
set -x

UBNTBOX_PATCHED="/tmp/fwupdate.real"
MD5FILE="/tmp/patchmd5"

cat <<EOF > ${MD5FILE}
c33235322da5baca5a7b237c09bc8df1  /sbin/fwupdate.real
EOF

# check md5 of files that will be patched
if ! md5sum -c ${MD5FILE}
then
        echo "******** Error when checking files. Refuse to do anything. ********"
        exit 0
fi

# prepare some overlay functionality
LOWERDIR="/tmp/lower_root"
mkdir -p ${LOWERDIR}
mount -t squashfs -oro /dev/mtdblock3 ${LOWERDIR}
overlay_some_path()
{
        PATH_TO_OVERLAY=$1
        ALIAS=$2
        UPPERDIR="/tmp/over_${ALIAS}"
        WORKDIR="/tmp/over_${ALIAS}_work"

        mkdir -p ${UPPERDIR}
        mkdir -p ${WORKDIR}

        mount -t overlay -o lowerdir=${LOWERDIR}${PATH_TO_OVERLAY},upperdir=${UPPERDIR},workdir=${WORKDIR} overlay ${PATH_TO_OVERLAY}
}

# patch the ubntbox binary.
overlay_some_path "/sbin" "sbin"
echo -en '\x10' | dd of=/sbin/fwupdate.real conv=notrunc bs=1 count=1 seek=24598

echo "******** Done ********"
``````

- Repack the configuration.
- Upload it via the normal web interface.
- Wait about a minute. The webserver should restart.
- Now there is a second web server at port 8080 which can call the lua
  script. Visit the page with a web browser. Link is for example
  http://192.168.1.1:8080/lua
- You should see the output of the script with a "*** Done ***" at the
  end. Note that the patches are not permanent. If you restart the
  router you have to re-visit the link (but not re-upload the config).
- Now you can upload an unsigned binary via the normal web interface.

e0382e88a9 ipq806x: build DEVICE_DTS based on SOC and device name
This patch uses the SOC variable to calculate DTS names automatically
based on the SOC and the device definition node name.

This reduces redundancy and (by having to choose DTS name
appropriately) will unify the naming of a device in different places
(image/Makefile, DTS name, compatible, image name). This is supposed
to make life easier for developers and reviewers.

Since the kernel uses a "soc-device.dts" scheme for this target, we
use this for the derivation of DEVICE_DTS, too, leaving the DTS names
unchanged for this target.

Note that for some devices the kernel itself uses inconsistent names
(DTS naming scheme vs. compatible), leaving us with a manual overwrite
of DEVICE_DTS for those cases.

09d38a3bc3 ramips: remove bogus ralink,mtd-eeprom with offset 0x4
Several devices in mt76x8 subtarget use the following line to set
up wmac in their DTS(I) files:

ralink,mtd-eeprom = <&factory 0x4>

This is strange for several reasons:
- They should use mediatek,mtd-eeprom on this SOC
- The caldata is supposed to start at 0x0
- The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway,
  starting from 0x0
- The offset coincides with the default location of the MAC address
  in caldata

Based on the comment in b28e94d4bf ("ramips: MiWiFi Nano fixes"),
it looks like the author for this device wanted to actually use
mtd-mac-address instead of ralink,mtd-eeprom. A check on the same
device revealed that actually the MAC address start at offset 4 there,
so the correct caldata offset is 0x0.

Based on these findings, and the fact that the expected location on
this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>"
statement from all devices in ramips (being only mt7628an anyway).

Thanks to Sungbo Eo for finding and researching this.

77f4d5c6bb ipq806x: rework ipq806x specific tsense temp driver
Tsense driver for ipq806x have various problem.
- Emit wrong error. On probing of this driver, nvmem driver can be
  not ready and this cause a EDEFER error. Actually this is not an
  error as the kernel will retry to probe the driver after the
  nvmem driver is loaded.
- Use uninitialized value on trigger of critical temp
- Doesn't free allocated memory

Because of this, rework the driver and improve it by removing extra
load of data.

Change the logic of loading data. Use the backup calib data only
when the calib data is not present. As the calibration is only
needed to set the temp offset, we don't really need to read
both calib data and set the offset based only on the backup one.
Also change how the notifier function work. At times when we
output the trigger message, we already have read the temp so
remove the extra read and the wrong uninitialized data that
probably caused a kernel panic for null pointer exception.
(Think we never experience this bug because the router
never reached that temp ever... So just lucky)

5ab9c0b388 ipq806x: fix bug in L2 cache scaling
It has been notice a buf in L2 cache scaling where the scaling is not
done proprely if the frequency is set to the initial state before
the new frequency.

From: https://patchwork.kernel.org/patch/10565443/

* The clocks are set to aux clock rate first to make sure the
* secondary mux is not sourcing off of QSB. The rate is then set to
* two different rates to force a HFPLL reinit under all
* circumstances.

In the initial stage of boot to force a new frequency to apply, is
needed to first set the frequency back to the lowest one (aux_rate)
and then to the target one. This force and make sure the controller
actually switch the frequency to the right one. Apply the same
mechanism to L2 frequency scaling. Before scaling to the target
frequency, first set the frequency to the aux_rate to force the
transition, then scale it to the target frequency. Doing the wrong way
can produce unexpected results and could lock the scaling mechanism
until a full reboot is done (Causing a full reset by the krait-cc driver)

From: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=77612720a2362230af726baa4149c40ec7a7fb05

When the Hfplls are reprogrammed during the rate change,
the primary muxes which are sourced from the same hfpll
for higher frequencies, needs to be switched to the 'safe
secondary mux' as the parent for that small window. This
is done by registering a clk notifier for the muxes and
switching to the safe parent in the PRE_RATE_CHANGE notifier
and back to the original parent in the POST_RATE_CHANGE notifier.

This should apply also to L2 scaling... as we can't relly use
the notifier, we manually do this on L2 scaling.
