Subject: [PATCH RFC 2/2] arm64: tegra: Add NVIDIA Jetson Nano 2GB Developer Kit support
Date: Sun, 08 Jun 2025 23:24:36 -0500 [thread overview]
Message-ID: <20250608-p3452-v1-2-4c2c1d7e4310@gmail.com> (raw)
In-Reply-To: <20250608-p3452-v1-0-4c2c1d7e4310@gmail.com>
From: Aaron Kling <webgeek1234@gmail.com>
This devkit is very similar to P3450, except it has less ram, no display
port, and only 3 usb host ports. Derive from P3450 and disable the
hardware that is unavailable.
