From 03f2b8eed73418269a158ccebad5d8d8f2f6daa1 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold stephan.gerhold@linaro.org Date: Wed, 19 Feb 2025 12:36:19 +0100 Subject: [PATCH] arm64: dts: qcom: x1e80100: Apply consistent critical thermal shutdown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
The firmware configures the TSENS controller with a maximum temperature of 120°C. When reaching that temperature, the hardware automatically triggers a reset of the entire platform. Some of the thermal zones in x1e80100.dtsi use a critical trip point of 125°C. It's impossible to reach those.
It's preferable to shut down the system cleanly before reaching the hardware trip point. Make the critical temperature trip points consistent by setting all of them to 115°C and apply a consistent hysteresis. The ACPI tables also specify 115°C as critical shutdown temperature.
