Subject: [PATCH] thermal: tegra: Add Tegra210B01 Support
Date: Sun, 18 Oct 2026 17:20:34 -0500 [thread overview]
Message-ID: <20261018-t210b01-thermal-v1-1-af15746d86a3@gmail.com> (raw)
From: Aaron Kling <webgeek1234@gmail.com>
Add Tegra210B01 SOC_THERM configuration. There are two main differences
from the original Tegra210:
* There is no mem thermal sensor
* Pdiv and pdiv_ate differ
Based-on: https://gitlab.com/nvidia/nv-tegra/linux-5.10/-/commit/b15149a15154e6b2fc827f4f169e37c9e5b389d9
