Subject: [PATCH 3/5] arm64: tegra: Add NVIDIA Jetson AGX Thor module EEPROM
Date: Fri, 18 Sep 2026 11:06:55 +0200 [thread overview]
Message-ID: <20260918-tegra264-i2c-v1-3-3adac7aae717@nvidia.com> (raw)
In-Reply-To: <20260918-tegra264-i2c-v1-0-3adac7aae717@nvidia.com>
From: Thierry Reding <treding@nvidia.com>
Like most previous Jetson devices, the Jetson AGX Thor has EEPROMs used
to identify the module. Add the device tree node describing this EEPROM.
