Flash instructions:
1. Gain ssh and serial port access, see the link below:
https://openwrt.org/toh/xiaomi/redmi_ax6000#installation
2. Use ssh or serial port to log in to the router, and
execute the following command:
nvram set boot_wait=on
nvram set flag_boot_rootfs=0
nvram set flag_boot_success=1
nvram set flag_last_success=1
nvram set flag_try_sys1_failed=8
nvram set flag_try_sys2_failed=8
nvram commit
3. Set a static ip on the ethernet interface of your computer
(e.g. default: ip 192.168.31.100, gateway 192.168.31.1)
4. Download the initramfs image, rename it to initramfs.bin,
and host it with the tftp server.
5. Interrupt U-Boot and run these commands:
setenv mtdparts nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),2048k(factory),2048k(fip),256k(crash),256k(crash_log),112640k(ubi)
saveenv
tftpboot initramfs.bin
bootm
6. After openwrt boots up, use scp or luci web
to upload sysupgrade.bin to upgrade.
Revert to stock firmware:
Restore mtdparts back to default, then use the
vendor's recovery tool (Windows only).

Endianness depends on CPU architecture. CONFIG_CPU_(BIG/LITTLE)_ENDIAN should
be enabled on target or subtarget based on SoC architecture.
Fixes warning:
$ make kernel_oldconfig CONFIG_TARGET=subtarget
...
.config:1008:warning: override: CPU_LITTLE_ENDIAN changes choice state
....
Summary:
- ARC - only the CONFIG_CPU_BIG_ENDIAN symbol is defined for this architeture.
If it is disabled then the processor operates in LITTLE_ENDIAN mode (default),
- ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This
option should be enabled after OpenWRT moves to kernel 6.x. After refreshing
the kernel, the symbol disappears,
- ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN,
- MIPS - enabled relevant symbols,
- POWERPC - enabled CONFIG_CPU_BIG_ENDIAN,
- UML - Symbols are not defined for this architecture,
- X86 - always little endian. Symbols are not defined for this architecture.

Add dependency to '32k' ADC clock so it is always enabled for thermal
and raw access to ADC values. This allows to remove the patch for the
ADC driver and reduce the patch adding thermal support for MT7986 to
only add the new efuse layout and temperature decoding for V3.

Remove kmod-sdhci-mtk as the mtk-sd driver is built-in anyway for the
relevant subtargets in order to support mounting rootfs from eMMC or
SD card.
Add kmod-iio-mt6577-auxadc to support reading the raw values from the
auxadc unit used as in-SoC thermal sensor. This driver was previously
built-in, but as thermal itself works well without it there is no use
for it in every day use of a device. Build the module to still allow
access to the raw values for those who need it.

Raising the temperatures for passive and active trips. @VA1DER
proposed at issue 9396 to remove passive trip. This commit relates to
his suggestion.
Without this patch. the CPU will be throttled all the way down to 98MHz
if the temperature rises even a degree above the trip point, and it was
further discovered that if the internal temperature of the device is
above the first trip point temperature when it boots then it will start
in a throttled state and even
$ echo disabled > /sys/class/thermal/thermal_zone0/mode
will have no effect.
The patch increases the passive trip point and active cooling map. The
throttling temperature will then be at 77°C and 82°C, which is still a
low enough temperature for ARM devices to not be in the real danger
zone, and gives some operational headroom.

When the v1 and v2 variants of the U6LR were introduced, the board
network config was not adapted to the new device names. Due to this, the
wrong network config is applied during initial boot. The resulting
config has lan, wan and a switch, while this device only has a single
ethernet interface without a switch.
Fix this by using a wildcard that matches all the variants.

The RGB LED of the UniFi 6 LR v1 doesn't work when using the Openwrt-

The LEDs connected to the MCU are so-called smart LEDs and their signal is

connected. It also means the LEDs could be individually controlled, if the MCU
has a command for this.

Or the comparison against a signed char is always true, because the
literal 0xaa is treated as an unsigned int, to which the signed char is
casted during comparison. 0xaa is above the positive values of a signed
char and negative signed char values result in values larger than 0xaa
when casted to unsigned int.

The patch 921-mt7986-add-mmc-support.patch introduced by commit
dabcaac443 ("mediatek: add mt7986 soc support to the target") has never
been applied in a way that it would have any effect as it actually
created a file target/linux/generic/patches-5.15/... in the kernel tree
and was probably a patch intended to be applied to openwrt.git instead
of being put into kernel patches folder as a file.
As an upstream commit from vanilla Linux also adding support for MT7986
to the mtk-sd driver has already been included we can remove that old
patch.
