Subject: arm64: dts: qcom: sdm630: Throttle the GPU when overheating
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=545fef1e5e43fb73083d16507a13820179726ebe;p=linux.git

arm64: dts: qcom: sdm630: Throttle the GPU when overheating

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.
