The SoM features: - eMMC - GNSS with 1PPS - V2X DSRC Radio - Secure Element for V2X Applications - Inertial Sensor - Pressure Sensor - Compass The HummingBoard Telematics carrier board features: - Cellular Modem - WiFi & Bluetooth - RTC with backup battery - CAN - 100Base-TX Ethernet - 100Base-T1 Ethernet - Multi-interface I/O connector - Multi-interface add-on board connector The multi-interface I/O connector supplies power and provides basic I/O (Console UART, 100Base-TX, 100Base-T1, CAN, and power-supply logic level GPIOs). The SolidRun Evaluation Kit includes a suitable cable and adapter board that breaks these out into RJ45, USB Type-A, microUSB Console, and Terminal Block connectors. The multi-interface add-on board connector provides additional interfaces (4x 100Base-T1, 2x SGMII, USB 2.0 shared with the cellular modem, CAN, MDIO, SPI, UART, PCIe, I2C, and GPIO). These add-on interfaces are disabled by default in the base device tree and are intended to be enabled and extended via device tree overlays. Note that a few components physically present on the SoM were omitted from this description due to a lack of upstream bindings and drivers: - Pressure Sensor - V2X DSRC Radio - Secure Element Acked-by: Andrew Lunn Signed-off-by: Josua Mayer --- arch/arm64/boot/dts/freescale/Makefile | 2 + .../freescale/imx8dxl-hummingboard-telematics.dts | 523 +++++++++++++++++++++ arch/arm64/boot/dts/freescale/imx8dxl-sr-som.dtsi | 458 ++++++++++++++++++ 3 files changed, 983 insertions(+) diff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index 711e36cc2c990..7db459f666610 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile @@ -111,6 +111,8 @@ dtb-$(CONFIG_ARCH_MXC) += imx8dxl-evk.dtb imx8dxl-evk-pcie-ep-dtbs += imx8dxl-evk.dtb imx-pcie0-ep.dtbo dtb-$(CONFIG_ARCH_MXC) += imx8dxl-evk-pcie-ep.dtb +DTC_FLAGS_imx8dxl-hummingboard-telematics := -@ +dtb-$(CONFIG_ARCH_MXC) += imx8dxl-hummingboard-telematics.dtb dtb-$(CONFIG_ARCH_MXC) += imx8dxp-tqma8xdp-mba8xx.dtb dtb-$(CONFIG_ARCH_MXC) += imx8dxp-tqma8xdps-mb-smarc-2.dtb diff --git a/arch/arm64/boot/dts/freescale/imx8dxl-hummingboard-telematics.dts b/arch/arm64/boot/dts/freescale/imx8dxl-hummingboard-telematics.dts new file mode 100644 index 0000000000000..7e822cbd7a528 --- /dev/null +++ b/arch/arm64/boot/dts/freescale/imx8dxl-hummingboard-telematics.dts @@ -0,0 +1,523 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright 2022-2026 Josua Mayer + */ + +/dts-v1/;
