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 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@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 $id: http://devicetree.org/schemas/usb/qcom,dwc3.yaml# This is not caused by the new device tree per se but comes from the usb@8af8800 node defined in ipq5018.dtsi. Running the check on 'qcom/ipq5018-rdp432-c2.dtb' shows the same. --- arch/arm64/boot/dts/qcom/Makefile | 1 + .../dts/qcom/ipq5018-tplink-archer-ax55-v1.dts | 128 +++++++++++++++++++++ 2 files changed, 129 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/Makefile b/arch/arm64/boot/dts/qcom/Makefile index 7d40ec5e7d214..c934e3aab2f44 100644 --- a/arch/arm64/boot/dts/qcom/Makefile +++ b/arch/arm64/boot/dts/qcom/Makefile @@ -10,6 +10,7 @@ dtb-$(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..5bb021cb29cd3 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/ipq5018-tplink-archer-ax55-v1.dts @@ -0,0 +1,128 @@ +// 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_ONLINE; + gpios = <&tlmm 11 GPIO_ACTIVE_HIGH>; + }; + + led-2 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_WLAN_2GHZ; + 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 { + color = <LED_COLOR_ID_GREEN>; + function = LED_FUNCTION_WLAN_5GHZ; + 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 = <&uart_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; + }; + + uart_pins: uart-pins-state { + pins = "gpio20", "gpio21"; + function = "blsp0_uart0"; + drive-strength = <8>; + bias-disable; + }; +}; + +&xo_board_clk { + clock-frequency = <24000000>; +}; -- 2.44.0
