Subject: [PATCH 2/4] arm64: dts: qcom: x1e80100: Apply consistent critical
thermal shutdown
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.
