Subject: [PATCH 0/5] arm64: tegra: Miscellaneous I2C changes on Tegra264
Date: Fri, 18 Sep 2026 11:06:52 +0200 [thread overview]
Message-ID: <20260918-tegra264-i2c-v1-0-3adac7aae717@nvidia.com> (raw)
This series of patches fixes some minor issues with the I2C controllers
on Tegra264 and adds some I2C clients that are useful for these systems.
Patch 1 adds the missing #address-cells and #size-cells properties for
all I2C controllers. These had gone unnoticed since no I2C clients had
been added so far.
Patch 2 ensures the I2C controllers are consistently named (and their
names correspond to those find in various documents) by adding aliases
to them.
The module and system EEPROMs found on most modern Jetson devices are
added in patches 3 and 4.
Finally, the thermal sensor found on the Jetson AGX Thor module is
described in patch 5. This allows reading the local temperature of the
module.
