[PATCH 04/12] arm64: dts: qcom: sdm845: Throttle the GPU when overheating

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
