BeagleBoard.org BeagleY-AI is an easy to use, affordable open source hardware single board computer based on the Texas Instruments AM67A, which features a quad-core 64-bit Arm CPU subsystem, 2 general-purpose digital-signal-processors (DSP) and matrix-multiply-accelerators (MMA), GPU, vision and deep learning accelerators, and multiple Arm Cortex-R5 cores for low-power, low-latency GPIO control. https://beagley-ai.org/ https://openbeagle.org/beagley-ai/beagley-ai Signed-off-by: Robert Nelson <robertcnelson@xxxxxxxxx> CC: Andrew Davis <afd@xxxxxx> CC: Nishanth Menon <nm@xxxxxx> CC: Jared McArthur <j-mcarthur@xxxxxx> CC: Jason Kridner <jkridner@xxxxxxxxxxxxxxx> CC: Deepak Khatri <lorforlinux@xxxxxxxxxxxxxxx> CC: Drew Fustini <drew@xxxxxxxxxxxxxxx> --- Changes since v1: - fixed incorrect vdd-3v3-sd-pins-default name - updated hdmi VDD_1V2 regulator for production pcb - switched device tree name from k3-j722s-beagley-ai to k3-am67a-beagley-ai - removed cpsw_port2 node - enable UHS support for MMCSD --- arch/arm64/boot/dts/ti/Makefile | 1 + .../arm64/boot/dts/ti/k3-am67a-beagley-ai.dts | 369 ++++++++++++++++++ 2 files changed, 370 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-am67a-beagley-ai.dts diff --git a/arch/arm64/boot/dts/ti/Makefile b/arch/arm64/boot/dts/ti/Makefile index 9a722c2473fb..a61e8902a23d 100644 --- a/arch/arm64/boot/dts/ti/Makefile +++ b/arch/arm64/boot/dts/ti/Makefile @@ -95,6 +95,7 @@ dtb-$(CONFIG_ARCH_K3) += k3-j721s2-evm.dtb dtb-$(CONFIG_ARCH_K3) += k3-j721s2-evm-pcie1-ep.dtbo # Boards with J722s SoC +dtb-$(CONFIG_ARCH_K3) += k3-am67a-beagley-ai.dtb dtb-$(CONFIG_ARCH_K3) += k3-j722s-evm.dtb # Boards with J784s4 SoC diff --git a/arch/arm64/boot/dts/ti/k3-am67a-beagley-ai.dts b/arch/arm64/boot/dts/ti/k3-am67a-beagley-ai.dts new file mode 100644 index 000000000000..cffa1c9ba00d --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-am67a-beagley-ai.dts @@ -0,0 +1,369 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/* + * https://beagley-ai.org/ + * + * Copyright (C) 2024 Texas Instruments Incorporated - https://www.ti.com/ + * Copyright (C) 2024 Robert Nelson, BeagleBoard.org Foundation + */ + +/dts-v1/;
