[PATCH 08/12] arm64: dts: qcom: sm8250: Throttle the GPU when overheating
From: Konrad Dybcio
Date: Fri May 10 2024 - 09:00:33 EST
Add an 85C passive trip point to ensure the thermal framework takes
sufficient action to prevent reaching junction temperature and a
110C critical point to help avoid hw damage.
