From: Thierry Reding <treding@xxxxxxxxxx> Add support for the combination of the NVIDIA Jetson Orin NX (P3767, SKU 0) module and the P3768 carrier board. Signed-off-by: Thierry Reding <treding@xxxxxxxxxx> --- Changes in v3: - move more nodes into the P3768 DTS include for better reusability Changes in v2: - fix system EEPROM I2C address - enable HDA because why not arch/arm64/boot/dts/nvidia/Makefile | 2 + .../nvidia/tegra234-p3768-0000+p3767-0000.dts | 134 ++++++++++ .../boot/dts/nvidia/tegra234-p3768-0000.dtsi | 245 ++++++++++++++++++ 3 files changed, 381 insertions(+) create mode 100644 arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767-0000.dts create mode 100644 arch/arm64/boot/dts/nvidia/tegra234-p3768-0000.dtsi diff --git a/arch/arm64/boot/dts/nvidia/Makefile b/arch/arm64/boot/dts/nvidia/Makefile index bc34c9d8846a..1406d5d40b8f 100644 --- a/arch/arm64/boot/dts/nvidia/Makefile +++ b/arch/arm64/boot/dts/nvidia/Makefile @@ -9,6 +9,7 @@ DTC_FLAGS_tegra194-p2972-0000 := -@ DTC_FLAGS_tegra194-p3509-0000+p3668-0000 := -@ DTC_FLAGS_tegra194-p3509-0000+p3668-0001 := -@ DTC_FLAGS_tegra234-p3737-0000+p3701-0000 := -@ +DTC_FLAGS_tegra234-p3768-0000+p3767-0000 := -@ dtb-$(CONFIG_ARCH_TEGRA_132_SOC) += tegra132-norrin.dtb dtb-$(CONFIG_ARCH_TEGRA_210_SOC) += tegra210-p2371-0000.dtb @@ -24,3 +25,4 @@ dtb-$(CONFIG_ARCH_TEGRA_194_SOC) += tegra194-p3509-0000+p3668-0000.dtb dtb-$(CONFIG_ARCH_TEGRA_194_SOC) += tegra194-p3509-0000+p3668-0001.dtb dtb-$(CONFIG_ARCH_TEGRA_234_SOC) += tegra234-sim-vdk.dtb dtb-$(CONFIG_ARCH_TEGRA_234_SOC) += tegra234-p3737-0000+p3701-0000.dtb +dtb-$(CONFIG_ARCH_TEGRA_234_SOC) += tegra234-p3768-0000+p3767-0000.dtb diff --git a/arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767-0000.dts b/arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767-0000.dts new file mode 100644 index 000000000000..7dfbc38eb3c4 --- /dev/null +++ b/arch/arm64/boot/dts/nvidia/tegra234-p3768-0000+p3767-0000.dts @@ -0,0 +1,134 @@ +// SPDX-License-Identifier: GPL-2.0 +/dts-v1/;
