Add support for the StartKit sk-imx53 board, a simple development board with the iMX536A SoC. Tested and works: - UARTs - SPI - I2C - GPU - USB - uSD - NAND - Ethernet Not tested: - Display - VPU - capture Not yet working: - Sound Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/imx53-sk-imx53.dts | 362 +++++++++++++++++++++++++++ 2 files changed, 363 insertions(+) create mode 100644 arch/arm/boot/dts/imx53-sk-imx53.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index d08a3c450ce7..d20fd01a8d07 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -465,6 +465,7 @@ dtb-$(CONFIG_SOC_IMX53) += \ imx53-ppd.dtb \ imx53-qsb.dtb \ imx53-qsrb.dtb \ + imx53-sk-imx53.dtb \ imx53-smd.dtb \ imx53-tx53-x03x.dtb \ imx53-tx53-x13x.dtb \ diff --git a/arch/arm/boot/dts/imx53-sk-imx53.dts b/arch/arm/boot/dts/imx53-sk-imx53.dts new file mode 100644 index 000000000000..392f6af59ecd --- /dev/null +++ b/arch/arm/boot/dts/imx53-sk-imx53.dts @@ -0,0 +1,362 @@ +// SPDX-License-Identifier: GPL-2.0+ +// +// Copyright 2023 Linaro Ltd. + +/dts-v1/;
