The LS1021A-TSN is a development board built by VVDN/Argonboards in partnership with NXP. It features the LS1021A SoC and the first-generation SJA1105T Ethernet switch for prototyping implementations of a subset of IEEE 802.1 TSN standards. It has two regular Ethernet ports and four switched, TSN-capable ports. It also features: - One Arduino header - One expansion header - Two USB 3.0 ports - One mini PCIe slot - One SATA interface - Accelerometer, gyroscope, temperature sensors Signed-off-by: Vladimir Oltean <olteanv@xxxxxxxxx> --- Changes from v1: - Applied Shawn's feedback - Introduced QSPI flash node v1 patch available at: https://patchwork.kernel.org/patch/10930451/ arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/ls1021a-tsn.dts | 288 ++++++++++++++++++++++++++++++ 2 files changed, 289 insertions(+) create mode 100644 arch/arm/boot/dts/ls1021a-tsn.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index dab2914fa293..a4eb4ca5e148 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -602,6 +602,7 @@ dtb-$(CONFIG_SOC_IMX7ULP) += \ dtb-$(CONFIG_SOC_LS1021A) += \ ls1021a-moxa-uc-8410a.dtb \ ls1021a-qds.dtb \ + ls1021a-tsn.dtb \ ls1021a-twr.dtb dtb-$(CONFIG_SOC_VF610) += \ vf500-colibri-eval-v3.dtb \ diff --git a/arch/arm/boot/dts/ls1021a-tsn.dts b/arch/arm/boot/dts/ls1021a-tsn.dts new file mode 100644 index 000000000000..b05774eac92e --- /dev/null +++ b/arch/arm/boot/dts/ls1021a-tsn.dts @@ -0,0 +1,288 @@ +// SPDX-License-Identifier: GPL-2.0 +/* Copyright 2016-2018 NXP Semiconductors + * Copyright 2019 Vladimir Oltean <olteanv@xxxxxxxxx> + */ + +/dts-v1/;
