Subject: [PATCH v4 2/2] arm64: dts: qcom: add TP-Link Archer AX55 v1
Add device tree source for the TP-Link Archer AX55 v1 [1]
which is a dual-band WiFi router based on the IPQ5018 SoC.
At the moment, only the UART, the GPIO LEDs and buttons
are usable, but it makes it possible to boot an initramfs
image on the device.
The device tree can be extended in the future, once support
for other periherals will be available for the platform.

Changes in v4:
- change the orange WAN LED's function to use LED_FUNCTION_WAN_ONLINE
definition introduced in v6.9-rc1
- remove function-enumerator properties from the WLAN LEDs and change
its' functions to use LED_FUNCTION_WLAN_[25]GHZ definitions introduced
in v6.9-rc1
- rebase on top of v6.9-rc1
Changes in v3:
- change pin configuration to use "gpio20" and "gpio21" for UART pins
- rebase on top of v6.8.
- Link to v2: https://lore.kernel.org/r/20240226-archer-ax55-v1-v2-2-3776eb61f432@gmail.com
Changes in v2:
- reorder the properties in TLMM pin configuration nodes to follow the
usual order pointed out by Krzysztof
- Link to v1: https://lore.kernel.org/all/20240223-archer-ax55-v1-v1-2-99f8fa2c3858@gmail.com
Note: running 'make CHECK_DTBS=y qcom/ipq5018-tplink-archer-ax55-v1.dtb'
shows the following:

This is not caused by the new device tree per se but comes from
the usb@...8800 node defined in ipq5018.dtsi. Running the check
on 'qcom/ipq5018-rdp432-c2.dtb' shows the same.
