xdp-tools build currently breaks on build hosts which do not have
libbpf headers installed because the build system wrongly tries to
use the host's include path.
Properly pass path to libbpf headers to xdp-tools build system to
fix build e.g. on the buildbots.

Add support for TP-Link Deco S4 wifi router
The label refers to the device as S4R and the TP-Link firmware
site calls it the Deco S4 v2. (There does not appear to be a v1)
Hardware (and FCC id) are identical to the Deco M4R v2 but the
flash layout is ordered differently and the OEM firmware encrypts
some config parameters (including the label mac address) in flash
In order to set the encrypted mac address, the wlan's caldata
node is removed from the DTS so the mac can be decrypted with
the help of the uencrypt tool and patched into the wlan fw
via hotplug
Specifications:
SoC: QCA9563-AL3A
RAM: Zentel A3R1GE40JBF
Wireless 2.4GHz: QCA9563-AL3A (main SoC)
Wireless 5GHz: QCA9886
Ethernet Switch: QCA8337N-AL3C
Flash: 16 MB SPI NOR
UART serial access (115200N1) on board via solder pads:
RX = TP1 pad
TX = TP2 pad
GND = C201 (pad nearest board edge)
The device's bootloader and web gui will only accept images that
were signed using TP-Link's RSA key, however a memory safety bug
in the bootloader can be leveraged to install openwrt without
accessing the serial console. See developer forum S4 support page

WatchGuard AP100 is an indoor wireless access point with
1 Gb ethernet port, dual-band but single-radio wireless,
internal antenna plates, and 802.3at PoE+
this board is a Senao device:
the hardware is equivalent to EnGenius EAP300 v2
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails
**Specification:**
- AR9344 SOC MIPS 74kc, 2.4 GHz AND 5 GHz WMAC, 2x2
- AR8035-A EPHY RGMII GbE with PoE+ IN
- 25 MHz clock
- 16 MB FLASH mx25l12805d
- 2x 64 MB RAM
- UART console J11, populated
- GPIO watchdog GPIO 16, 20 sec toggle
- 2 antennas 5 dBi, internal omni-directional plates
- 5 LEDs power, eth0 link/data, 2G, 5G
- 1 button reset
**MAC addresses:**
Label has no MAC
Only one Vendor MAC address in flash at art 0x0
eth0 ---- *:e5 art 0x0 -2
phy0 ---- *:e5 art 0x0 -2
**Installation:**
Method 1: OEM webpage
use OEM webpage for firmware upgrade to upload factory.bin
Method 2: root shell
It may be necessary to use a Watchguard router to flash the image to the AP
and / or to downgrade the software on the AP to access SSH
For some Watchguard devices, serial console over UART is disabled.
NOTE: DHCP is not enabled by default after flashing
**TFTP recovery:**
reset button has no function at boot time
only possible with modified uboot environment,
(see commit message for Watchguard AP300)
**Return to OEM:**
user should make backup of MTD partitions
and write the backups back to mtd devices
in order to revert to OEM reliably
It may be possible to use sysupgrade
with an OEM image as well...
(not tested)
**OEM upgrade info:**
The OEM upgrade script is at /etc/fwupgrade.sh
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1536k
and the factory.bin upgrade procedure would otherwise
overwrite part of the kernel when writing rootfs.
**Note on eth0 PLL-data:**
The default Ethernet Configuration register values will not work
because of the external AR8035 switch between
the SOC and the ethernet port.
For AR934x series, the PLL registers for eth0
can be see in the DTSI as 0x2c.
Therefore the PLL registers can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x1805002c 1`.
The clock delay required for RGMII can be applied
at the PHY side, using the at803x driver `phy-mode`.
Therefore the PLL registers for GMAC0
do not need the bits for delay on the MAC side.
This is possible due to fixes in at803x driver
since Linux 5.1 and 5.3
**Note on WatchGuard Magic string:**
The OEM upgrade script is a modified version of
the generic Senao sysupgrade script
which is used on EnGenius devices.
On WatchGuard boards produced by Senao,
images are verified using a md5sum checksum of
the upgrade image concatenated with a magic string.
this checksum is then appended to the end of the final image.
This variable does not apply to all the senao devices
so set to null string as default

and verify that it is correct with
fw_printenv
then, before boot, the device will attempt TFTP from 192.168.1.101
looking for file 'test.bin'
to return uboot environment to normal:

The image build process was modifying the generated IMAGE_KERNEL to
append rootfs information (crc). This caused:
- sysupgrade & factory images to contain 2 times the root.squashfs
information due to both modifying the same IMAGE_KERNEL.
- the generated imagebuilder to contain an erroneous IMAGE_KERNEL that
contained references to an unexisting root.squashfs (the one from
previous cause). The RTL30VW wasn't therefore able to boot the
generated images as they contained checksums from non existing rootfs.
This commit makes sure to use a temporary IMAGE_KERNEL to append the
rootfs information for both factory and sysupgrade images.

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
adapter, TFTP server, and removing a single T10 screw,
but with much less manual steps, and is generally recommended, being
safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
work on some rare versions of stock firmware. A more involved, and
requires installing `mkenvimage` from u-boot-tools package if you
choose to rebuild your own environment, but can be used without
disassembly or removal from installation point, if you have the
credentials.
If for some reason, size of your sysupgrade image exceeds 13312kB,
proceed with method [1]. For official images this is not likely to
happen ever.
[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
does not back-power the board, otherwise it will fail to boot.
1. Power-on the board. Then quickly connect serial converter to PC and
hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
you'll enter U-boot shell. Then skip to point 3.
Connection parameters are 115200-8-N-1.
2. Allow the board to boot. Press the reset button, so the board
reboots into U-boot again and go back to point 1.
3. Set the "bootcmd" variable to disable the dual-boot feature of the
system and ensure that uImage is loaded. This is critical step, and
needs to be done only on initial installation.
> setenv bootcmd "bootm 0x9f040000"
> saveenv
4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:
> setenv serverip 192.168.1.2
> setenv ipaddr 192.168.1.1
> tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7321-initramfs-kernel.bin
> bootm 0x81000000
5. Optional, but highly recommended: back up contents of "firmware" partition:
$ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7321_fw1_backup.bin
$ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7321_fw2_backup.bin
6. Copy over sysupgrade image, and perform actual installation. OpenWrt
shall boot from flash afterwards:
$ ssh root@192.168.1.1
# sysupgrade -n openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin
[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
it boots, hold the reset button near Ethernet connectors for 5
seconds.
1. Connect the device to the network. It will acquire address over DHCP,
so either find its address using list of DHCP leases by looking for
label MAC address, or try finding it by scanning for SSH port:
$ nmap 10.42.0.0/24 -p22
From now on, we assume your computer has address 10.42.0.1 and the device
has address 10.42.0.254.
2. Set up a TFTP server on your computer. We assume that TFTP server
root is at /srv/tftp.
3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
frmware is pretty ancient and requires enabling HMAC-MD5.
$ ssh 10.42.0.254 \
-o UserKnownHostsFile=/dev/null \
-o StrictHostKeyCheking=no \
-o MACs=hmac-md5
Login. User is "super", password is "sp-admin".
Now execute a hidden command:
Ruckus
It is case-sensitive. Copy and paste the following string,
including quotes. There will be no output on the console for that.
";/bin/sh;"
Hit "enter". The AP will respond with:
grrrr
OK
Now execute another hidden command:
!v54!
At "What's your chow?" prompt just hit "enter".
Congratulations, you should now be dropped to Busybox shell with root
permissions.
4. Optional, but highly recommended: backup the flash contents before
installation. At your PC ensure the device can write the firmware
over TFTP:
$ sudo touch /srv/tftp/ruckus_zf7321_firmware{1,2}.bin
$ sudo chmod 666 /srv/tftp/ruckus_zf7321_firmware{1,2}.bin
Locate partitions for primary and secondary firmware image.
NEVER blindly copy over MTD nodes, because MTD indices change
depending on the currently active firmware, and all partitions are
writable!
# grep rcks_wlan /proc/mtd
Copy over both images using TFTP, this will be useful in case you'd
like to return to stock FW in future. Make sure to backup both, as
OpenWrt uses bot firmwre partitions for storage!
# tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7321_firmware1.bin -p 10.42.0.1
# tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7321_firmware2.bin -p 10.42.0.1
When the command finishes, copy over the dump to a safe place for
storage.
$ cp /srv/tftp/ruckus_zf7321_firmware{1,2}.bin ~/
5. Ensure the system is running from the BACKUP image, i.e. from
rcks_wlan.bkup partition or "image 2". Otherwise the installation
WILL fail, and you will need to access mtd0 device to write image
which risks overwriting the bootloader, and so is not covered here
and not supported.
Switching to backup firmware can be achieved by executing a few
consecutive reboots of the device, or by updating the stock firmware. The
system will boot from the image it was not running from previously.
Stock firmware available to update was conveniently dumped in point 4 :-)
6. Prepare U-boot environment image.
Install u-boot-tools package. Alternatively, if you build your own
images, OpenWrt provides mkenvimage in host staging directory as well.
It is recommended to extract environment from the device, and modify
it, rather then relying on defaults:
$ sudo touch /srv/tftp/u-boot-env.bin
$ sudo chmod 666 /srv/tftp/u-boot-env.bin
On the device, find the MTD partition on which environment resides.
Beware, it may change depending on currently active firmware image!
# grep u-boot-env /proc/mtd
Now, copy over the partition
# tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1
Store the stock environment in a safe place:
$ cp /srv/tftp/u-boot-env.bin ~/
Extract the values from the dump:
$ strings u-boot-env.bin | tee u-boot-env.txt
Now clean up the debris at the end of output, you should end up with
each variable defined once. After that, set the bootcmd variable like
this:
bootcmd=bootm 0x9f040000
You should end up with something like this:
bootcmd=bootm 0x9f040000
bootargs=console=ttyS0,115200 rootfstype=squashfs init=/sbin/init
baudrate=115200
ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee
mtdparts=mtdparts=ar7100-nor0:256k(u-boot),13312k(rcks_wlan.main),2048k(datafs),256k(u-boot-env),512k(Board Data),13312k(rcks_wlan.bkup)
mtdids=nor0=ar7100-nor0
bootdelay=2
ethact=eth0
filesize=78a000
fileaddr=81000000
partition=nor0,0
mtddevnum=0
mtddevname=u-boot
ipaddr=10.0.0.1
serverip=10.0.0.5
stdin=serial
stdout=serial
stderr=serial
These are the defaults, you can use most likely just this as input to
mkenvimage.
Now, create environment image and copy it over to TFTP root:
$ mkenvimage -s 0x40000 -b -o u-boot-env.bin u-boot-env.txt
$ sudo cp u-boot-env.bin /srv/tftp
This is the same image, gzipped and base64-encoded:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
TFTP root:
$ sudo cp openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin /srv/tftp
Now load both to the device over TFTP:
# tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
# tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin -g 10.42.0.1
Vverify checksums of both images to ensure the transfer over TFTP
was completed:
# sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin
And compare it against source images:
$ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7321-squashfs-sysupgrade.bin
Locate MTD partition of the primary image:
# grep rcks_wlan.main /proc/mtd
Now, write the images in place. Write U-boot environment last, so
unit still can boot from backup image, should power failure occur during
this. Replace MTD placeholders with real MTD nodes:
# flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
# flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>
Finally, reboot the device. The device should directly boot into
OpenWrt. Look for the characteristic power LED blinking pattern.
# reboot -f
After unit boots, it should be available at the usual 192.168.1.1/24.
Return to factory firmware:
1. Boot into OpenWrt initramfs as for initial installation. To do that
without disassembly, you can write an initramfs image to the device
using 'sysupgrade -F' first.
2. Unset the "bootcmd" variable:
fw_setenv bootcmd ""
3. Write factory images downloaded from manufacturer website into
fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
before installation:
mtd write ruckus_zf7321_fw1_backup.bin /dev/mtd1
mtd write ruckus_zf7321_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.
Quirks and known issues:
- Flash layout is changed from the factory, to use both firmware image
partitions for storage using mtd-concat, and uImage format is used to
actually boot the system, which rules out the dual-boot capability.
- The 5GHz radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
OpenWrt by choice.
It is controlled by data in the top 64kB of RAM which is unmapped,
to avoid the interference in the boot process and accidental
switch to the inactive image, although boot script presence in
form of "bootcmd" variable should prevent this entirely.
- U-boot disables JTAG when starting. To re-enable it, you need to
execute the following command before booting:
mw.l 1804006c 40
And also you need to disable the reset button in device tree if you
intend to debug Linux, because reset button on GPIO0 shares the TCK
pin.
- On some versions of stock firmware, it is possible to obtain root shell,
however not much is available in terms of debugging facitilies.
1. Login to the rkscli
2. Execute hidden command "Ruckus"
3. Copy and paste ";/bin/sh;" including quotes. This is required only
once, the payload will be stored in writable filesystem.
4. Execute hidden command "!v54!". Press Enter leaving empty reply for
"What's your chow?" prompt.
5. Busybox shell shall open.

Installation:
There are two methods of installation:
- Using serial console [1] - requires some disassembly, 3.3V USB-Serial
adapter, TFTP server, and removing a single T10 screw,
but with much less manual steps, and is generally recommended, being
safer.
- Using stock firmware root shell exploit, SSH and TFTP [2]. Does not
work on some rare versions of stock firmware. A more involved, and
requires installing `mkenvimage` from u-boot-tools package if you
choose to rebuild your own environment, but can be used without
disassembly or removal from installation point, if you have the
credentials.
If for some reason, size of your sysupgrade image exceeds 13312kB,
proceed with method [1]. For official images this is not likely to
happen ever.
[1] Using serial console:
0. Connect serial console to H1 header. Ensure the serial converter
does not back-power the board, otherwise it will fail to boot.
1. Power-on the board. Then quickly connect serial converter to PC and
hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
you'll enter U-boot shell. Then skip to point 3.
Connection parameters are 115200-8-N-1.
2. Allow the board to boot. Press the reset button, so the board
reboots into U-boot again and go back to point 1.
3. Set the "bootcmd" variable to disable the dual-boot feature of the
system and ensure that uImage is loaded. This is critical step, and
needs to be done only on initial installation.
> setenv bootcmd "bootm 0x9f040000"
> saveenv
4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed:
> setenv serverip 192.168.1.2
> setenv ipaddr 192.168.1.1
> tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7372-initramfs-kernel.bin
> bootm 0x81000000
5. Optional, but highly recommended: back up contents of "firmware" partition:
$ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7372_fw1_backup.bin
$ ssh root@192.168.1.1 cat /dev/mtd5 > ruckus_zf7372_fw2_backup.bin
6. Copy over sysupgrade image, and perform actual installation. OpenWrt
shall boot from flash afterwards:
$ ssh root@192.168.1.1
# sysupgrade -n openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin
[2] Using stock root shell:
0. Reset the device to factory defaullts. Power-on the device and after
it boots, hold the reset button near Ethernet connectors for 5
seconds.
1. Connect the device to the network. It will acquire address over DHCP,
so either find its address using list of DHCP leases by looking for
label MAC address, or try finding it by scanning for SSH port:
$ nmap 10.42.0.0/24 -p22
From now on, we assume your computer has address 10.42.0.1 and the device
has address 10.42.0.254.
2. Set up a TFTP server on your computer. We assume that TFTP server
root is at /srv/tftp.
3. Obtain root shell. Connect to the device over SSH. The SSHD ond the
frmware is pretty ancient and requires enabling HMAC-MD5.
$ ssh 10.42.0.254 \
-o UserKnownHostsFile=/dev/null \
-o StrictHostKeyCheking=no \
-o MACs=hmac-md5
Login. User is "super", password is "sp-admin".
Now execute a hidden command:
Ruckus
It is case-sensitive. Copy and paste the following string,
including quotes. There will be no output on the console for that.
";/bin/sh;"
Hit "enter". The AP will respond with:
grrrr

At "What's your chow?" prompt just hit "enter".
Congratulations, you should now be dropped to Busybox shell with root
permissions.
4. Optional, but highly recommended: backup the flash contents before
installation. At your PC ensure the device can write the firmware
over TFTP:
$ sudo touch /srv/tftp/ruckus_zf7372_firmware{1,2}.bin
$ sudo chmod 666 /srv/tftp/ruckus_zf7372_firmware{1,2}.bin
Locate partitions for primary and secondary firmware image.
NEVER blindly copy over MTD nodes, because MTD indices change
depending on the currently active firmware, and all partitions are
writable!
# grep rcks_wlan /proc/mtd
Copy over both images using TFTP, this will be useful in case you'd
like to return to stock FW in future. Make sure to backup both, as
OpenWrt uses bot firmwre partitions for storage!
# tftp -l /dev/<rcks_wlan.main_mtd> -r ruckus_zf7372_firmware1.bin -p 10.42.0.1
# tftp -l /dev/<rcks_wlan.bkup_mtd> -r ruckus_zf7372_firmware2.bin -p 10.42.0.1
When the command finishes, copy over the dump to a safe place for
storage.
$ cp /srv/tftp/ruckus_zf7372_firmware{1,2}.bin ~/
5. Ensure the system is running from the BACKUP image, i.e. from
rcks_wlan.bkup partition or "image 2". Otherwise the installation
WILL fail, and you will need to access mtd0 device to write image
which risks overwriting the bootloader, and so is not covered here

# grep u-boot-env /proc/mtd
Now, copy over the partition
# tftp -l /dev/mtd<N> -r u-boot-env.bin -p 10.42.0.1
Store the stock environment in a safe place:
$ cp /srv/tftp/u-boot-env.bin ~/
Extract the values from the dump:
$ strings u-boot-env.bin | tee u-boot-env.txt
Now clean up the debris at the end of output, you should end up with
each variable defined once. After that, set the bootcmd variable like
this:
bootcmd=bootm 0x9f040000
You should end up with something like this:

7. Perform actual installation. Copy over OpenWrt sysupgrade image to
TFTP root:
$ sudo cp openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin /srv/tftp
Now load both to the device over TFTP:
# tftp -l /tmp/u-boot-env.bin -r u-boot-env.bin -g 10.42.0.1
# tftp -l /tmp/openwrt.bin -r openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin -g 10.42.0.1
Verify checksums of both images to ensure the transfer over TFTP
was completed:
# sha256sum /tmp/u-boot-env.bin /tmp/openwrt.bin
And compare it against source images:
$ sha256sum /srv/tftp/u-boot-env.bin /srv/tftp/openwrt-ath79-generic-ruckus_zf7372-squashfs-sysupgrade.bin
Locate MTD partition of the primary image:
# grep rcks_wlan.main /proc/mtd
Now, write the images in place. Write U-boot environment last, so
unit still can boot from backup image, should power failure occur during
this. Replace MTD placeholders with real MTD nodes:
# flashcp /tmp/openwrt.bin /dev/<rcks_wlan.main_mtd>
# flashcp /tmp/u-boot-env.bin /dev/<u-boot-env_mtd>
Finally, reboot the device. The device should directly boot into
OpenWrt. Look for the characteristic power LED blinking pattern.
# reboot -f

3. Write factory images downloaded from manufacturer website into
fwconcat0 and fwconcat1 MTD partitions, or restore backup you took
before installation:
mtd write ruckus_zf7372_fw1_backup.bin /dev/mtd1
mtd write ruckus_zf7372_fw2_backup.bin /dev/mtd5
4. Reboot the system, it should load into factory firmware again.
Quirks and known issues:
- This is first device in ath79 target to support link state reporting
on FE port attached trough the built-in switch.
- Flash layout is changed from the factory, to use both firmware image
partitions for storage using mtd-concat, and uImage format is used to
actually boot the system, which rules out the dual-boot capability.
The 5GHz radio has its own EEPROM on board, not connected to CPU.

And also you need to disable the reset button in device tree if you
intend to debug Linux, because reset button on GPIO0 shares the TCK
pin.
- On some versions of stock firmware, it is possible to obtain root shell,
however not much is available in terms of debugging facitilies.

- Stock firmware has beamforming functionality, known as BeamFlex,
using active multi-segment antennas on both bands - controlled by
RF analog switches, driven by a pair of 74LV164 shift registers.
Shift registers used for each radio are connected to GPIO14 (clock)
and GPIO15 of the respective chip.
They are mapped as generic GPIOs in OpenWrt - in stock firmware,
they were most likely handled directly by radio firmware,
given the real-time nature of their control.
Lack of this support in OpenWrt causes the antennas to behave as
ordinary omnidirectional antennas, and does not affect throughput in
normal conditions, but GPIOs are available to tinker with nonetheless.

Return to using the OpenWrt kernel loader to decompress and load kernel
initram image.
Continue to use the vmlinuz kernel for squashfs.
Mikrotik's bootloader RouterBOOT on some ath79 devices is
failing to boot the current initram, due to the size of the initram image.
On the ath79 wAP-ac:
a 5.7MiB initram image would fail to boot
After this change:
a 6.6MiB initram image successfully loads
This partially reverts commit e91344776b.
An alternative of using RouterBOOT's capability of loading an initrd ELF
section was investigated, but the OpenWrt kernel loader allows larger image.

End-users may need to be able to rewrite u-boot configuration on the
WS-AP3825i, which has had repeated issues with the exact configuration
of u-boot, e.g. commit 1d06277407 ("mpc85xx: Fix output location of
padded dtb") (alongside other failures documented for example in this
post[^1] from the main AP3825i porting thread).
To assist with this, remove the `read-only` property from the u-boot
configuration partitions cfg1 and cfg2.

Backports patch, which is currently on review [1] for kernel 5.10 and
kernel 5.15, where it applies cleanly. This was tested on CZ.NIC Turris
1.1 router running OpenWrt 21.02.03 with kernel 5.15.
Before:
- In /var/log/messages:
```
[ 16.392988] lm90 0-004c: cannot request IRQ 48
[ 16.398280] lm90: probe of 0-004c failed with error -22
```
- Sensors does not work:
```
root@turris:~# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
```
After:
```
root@turris:/# sensors
sa56004-i2c-0-4c
Adapter: MPC adapter (i2c@3000)
temp1: +44.0°C (low = +0.0°C, high = +70.0°C)
(crit = +85.0°C, hyst = +75.0°C)
temp2: +73.8°C (low = +0.0°C, high = +70.0°C) ALARM (HIGH)
(crit = +85.0°C, hyst = +75.0°C)
```
