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. 1. https://www.tp-link.com/en/home-networking/wifi-router/archer-ax55/v1/ Signed-off-by: Gabor Juhos <j4g8y7@xxxxxxxxx> --- 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@xxxxxxxxx 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@xxxxxxxxx Note: running 'make CHECK_DTBS=y qcom/ipq5018-tplink-archer-ax55-v1.dtb' shows the following: DTC_CHK arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb <...>/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb: usb@8af8800: interrupts: [[0, 62, 4]] is too short from schema $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# <...>/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb: usb@8af8800: interrupt-names: ['hs_phy_irq'] is too short from schema $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# <...>/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb: usb@8af8800: interrupts: [[0, 62, 4]] is too short from schema $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# <...>/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb: usb@8af8800: interrupt-names:0: 'pwr_event' was expected from schema $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# <...>/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dtb: usb@8af8800: interrupt-names: ['hs_phy_irq'] is too short from schema $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# This is not caused by the new device tree per se but comes from the usb@8af8800 node defined in ipq5018.dtsi.
