From b79dd56ed5fcc863f167eb53771b09e8b3d8e317 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Fri, 10 May 2024 14:58:33 +0200 Subject: [PATCH] arm64: dts: qcom: sdm845: 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.
