Subject: [PATCH 3/4] arm64: tegra: Add Jetson Orin NX support
Date: Thu, 2 Mar 2023 10:33:52 +0100 [thread overview]
Message-ID: <20230302093353.3873247-3-thierry.reding@gmail.com> (raw)
In-Reply-To: <20230302093353.3873247-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
This adds a device tree for the Jetson Orin NX module, which is Jetson
AGX Orin's little sibling with 6 or 8 ARM Cortex-A78AE cores, an Ampere
GPU (1024 GPU and 32 tensor cores) and a number of accelerators for
machine learning, image processing and more.
The Jetson Orin NX comes with either 8 or 16 GiB of 128-bit LPDDR5 and
supports NVME for mass storage.
