Some boards have SD card connectors where the power rail cannot be switched
off by the driver. If the card has not been power cycled, it may still be
using 1.8V signaling after a warm re-boot. Bootroms expecting 3.3V signaling
will fail to boot from a UHS card that continue to use 1.8V signaling.
Set initial signal voltage in mmc_power_off() to allow re-boot to function.
This fixes re-boot with UHS cards on Asus Tinker Board (Rockchip RK3288),
same issue have been seen on some Rockchip RK3399 boards.

Obtain SSH Access
1. Download and flash the firmware version 1.3.8 (China).
2. Login to the router web interface and get the value of `stok=` from the
URL
3. Open a new tab and go to the following URL (replace <STOK> with the stok
value gained above; line breaks are only for easier handling, please put
together all four lines into a single URL without any spaces):
http://192.168.31.1/cgi-bin/luci/;stok=<STOK>/api/misystem/set_config_iotdev
?bssid=any&user_id=any&ssid=-h%0Anvram%20set%20ssh_en%3D1%0Anvram%20commit
%0Ased%20-i%20%27s%2Fchannel%3D.%2A%2Fchannel%3D%5C%5C%22debug%5C%5C%22%2F
g%27%20%2Fetc%2Finit.d%2Fdropbear%0A%2Fetc%2Finit.d%2Fdropbear%20start%0A
4. Wait 30-60 seconds (this is the time required to generate keys for the
SSH server on the router).
Create Full Backup
1. Obtain SSH Access.
2. Create backup of all flash (on router):
dd if=/dev/mtd0 of=/tmp/ALL.backup
3. Copy backup to PC (on PC):
scp root@192.168.31.1:/tmp/ALL.backup ./
Tip: backup of the original firmware, taken three times, increases the
chances of recovery :)
Calculate The Password
* Locally using shell (replace "12345/E0QM98765" with your router's serial
number):
On Linux
printf "%s6d2df50a-250f-4a30-a5e6-d44fb0960aa0" "12345/E0QM98765" | \
md5sum - | head -c8 && echo
On macOS
printf "%s6d2df50a-250f-4a30-a5e6-d44fb0960aa0" "12345/E0QM98765" | \
md5 | head -c8
* Locally using python script (replace "12345/E0QM98765" with your
router's serial number):
wget https://raw.githubusercontent.com/eisaev/ax3600-files/master/scripts/calc_passwd.py
python3.7 -c 'from calc_passwd import calc_passwd; print(calc_passwd("12345/E0QM98765"))'
* Online

Debricking (lite)
If you have a healthy bootloader, you can use recovery via TFTP using
programs like TinyPXE on Windows or dnsmasq on Linux. To switch the router
to TFTP recovery mode, hold down the reset button, connect the power
supply, and release the button after about 10 seconds. The router must be
connected directly to the PC via the LAN port.
Debricking
You will need a full dump of your flash, a CH341 programmer, and a clip
for in-circuit programming.
Install OpenWRT
1. Obtain SSH Access.
2. Create script (on router):
echo '#!/bin/sh' > /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
echo '. /bin/boardupgrade.sh' >> /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
echo 'board_prepare_upgrade' >> /tmp/flash_fw.sh
echo 'mtd erase rootfs_data' >> /tmp/flash_fw.sh
echo 'mtd write /tmp/openwrt.bin firmware' >> /tmp/flash_fw.sh
echo 'sleep 3' >> /tmp/flash_fw.sh
echo 'reboot' >> /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
chmod +x /tmp/flash_fw.sh
3. Copy `openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin`
to the router (on PC):
scp openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin \
root@192.168.31.1:/tmp/openwrt.bin
4. Flash OpenWRT (on router):
/bin/ash /tmp/flash_fw.sh &
5. SSH connection will be interrupted - this is normal.
6. Wait for the indicator to turn blue.

* ipq806x: fix missing changes in 5.4 for new cpufreq implementation
The new cpufreq dedicated driver changed the node structure
on how the cache should be defined in the dts. The 5.4 dtsi addition
patch has not been updated to follow the new implementation.
Fix this to restore correct cache scaling and restore any performance
regression.

* ipq806x: fix missing 1.4ghz cache freq for ipq8065 SoC
With the new implementation of the dedicated cpufreq driver,
the 1.4 Ghz was only dropped and not added to the ipq8065 SoC.
Fix this to improve performance.

* ipq806x: fix dedicated cpufreq driver
2 small fix for the dedicated cpufreq driver:
- Fix index wrongly used as the current cpu
- Exit early if a bad freq is detected. In the current state the freq
is applied anyway even with invalid state.
