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 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 --- arch/arm64/boot/dts/qcom/Makefile | 1 + .../dts/qcom/ipq5018-tplink-archer-ax55-v1.dts | 133 +++++++++++++++++++++ 2 files changed, 134 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/Makefile b/arch/arm64/boot/dts/qcom/Makefile index 39889d5f8e123..d3ba1e22d6ddd 100644 --- a/arch/arm64/boot/dts/qcom/Makefile +++ b/arch/arm64/boot/dts/qcom/Makefile @@ -10,6 +10,7 @@ dtb-$(CONFIG_ARCH_QCOM) += apq8094-sony-xperia-kitakami-karin_windy.dtb dtb-$(CONFIG_ARCH_QCOM) += apq8096-db820c.dtb dtb-$(CONFIG_ARCH_QCOM) += apq8096-ifc6640.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq5018-rdp432-c2.dtb +dtb-$(CONFIG_ARCH_QCOM) += ipq5018-tplink-archer-ax55-v1.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq5332-rdp441.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq5332-rdp442.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq5332-rdp468.dtb diff --git a/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dts b/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dts new file mode 100644 index 0000000000000..10fff50bb8161 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dts @@ -0,0 +1,133 @@ +// SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause + +/dts-v1/; + +#include <dt-bindings/gpio/gpio.h> +#include <dt-bindings/input/input.h> +#include <dt-bindings/leds/common.h> + +#include "ipq5018.dtsi" + +/ { + model = "TP-Link Archer AX55 v1"; + compatible = "tplink,archer-ax55-v1", "qcom,ipq5018"; + + aliases { + serial0 = &blsp1_uart1; + }; + + chosen { + stdout-path = "serial0:115200n8"; + }; + + leds { + compatible = "gpio-leds"; + pinctrl-0 = <&led_pins>; + pinctrl-names = "default"; + + led-0 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_LAN; + gpios = <&tlmm 10 GPIO_ACTIVE_HIGH>; + }; + + led-1 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_WAN; + gpios = <&tlmm 11 GPIO_ACTIVE_HIGH>; + }; + + led-2 { + /* WLAN 2.4GHz */ + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_WLAN; + function-enumerator = <0>; + gpios = <&tlmm 13 GPIO_ACTIVE_HIGH>; + }; + + led-3 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_POWER; + gpios = <&tlmm 18 GPIO_ACTIVE_HIGH>; + }; + + led-4 { + color = <LED_COLOR_ID_ORANGE>; + function = LED_FUNCTION_WAN; + gpios = <&tlmm 22 GPIO_ACTIVE_HIGH>; + }; + + led-5 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_USB; + gpios = <&tlmm 38 GPIO_ACTIVE_HIGH>; + }; + + led-6 { + /* WLAN 5GHz */ + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_WLAN; + function-enumerator = <1>; + gpios = <&tlmm 39 GPIO_ACTIVE_HIGH>; + }; + }; + + buttons { + compatible = "gpio-keys"; + pinctrl-0 = <&button_pins>; + pinctrl-names = "default"; + + button-reset { + debounce-interval = <60>; + gpios = <&tlmm 25 GPIO_ACTIVE_LOW>; + label = "reset"; + linux,code = <KEY_RESTART>; + }; + + button-wps { + debounce-interval = <60>; + gpios = <&tlmm 31 GPIO_ACTIVE_LOW>; + label = "wps"; + linux,code = <KEY_WPS_BUTTON>; + }; + }; +}; + +&blsp1_uart1 { + pinctrl-0 = <&uart1_pins>; + pinctrl-names = "default"; + status = "okay"; +}; + +&sleep_clk { + clock-frequency = <32000>; +}; + +&tlmm { + button_pins: button-pins-state { + pins = "gpio25", "gpio31"; + function = "gpio"; + drive-strength = <8>; + bias-pull-up; + }; + + led_pins: led-pins-state { + pins = "gpio10", "gpio11", "gpio13", "gpio18", "gpio22", + "gpio38", "gpio39"; + function = "gpio"; + drive-strength = <2>; + bias-disable; + }; +}; + +&uart1_pins { + /* + * Remove "gpio31" from the default pins in order to be able + * to use that for the WPS button. + */ + pins = "gpio32", "gpio33", "gpio34"; +}; + +&xo_board_clk { + clock-frequency = <24000000>; +}; -- 2.43.2
