Subject: [PATCH v3 13/13] arm64: defconfig: Enable I3C and SPD5118 hwmon
Date: Thu, 23 Apr 2026 14:27:12 +0530	[thread overview]
Message-ID: <20260423085718.70762-14-akhilrajeev@nvidia.com> (raw)
In-Reply-To: <20260423085718.70762-1-akhilrajeev@nvidia.com>

Enable I3C subsystem (I3C), Synopsys DesignWare I3C master controller
(DW_I3C_MASTER), and SPD5118 hwmon temperature sensor (SENSORS_SPD5118)
as modules.

The NVIDIA Vera CPU uses SOCAMM LPDDR5X memory module, which contain
SPD5118 (JEDEC JESD300) compliant temperature sensor. This sensor is
accessible over the I3C bus through the DesignWare I3C controller present
on the SoC. Enabling these configs allows monitoring memory module
temperatures on platforms such as Vera Rubin. Vera is an ACPI-based
platform and does not use device tree.
